Aside - This post has received many tangential questions in the comments. Your best bet at getting an answer to those questions is to check Stack Overflow and/or post your question there.

A while ago in one of my older posts I included a little gem that I think deserves it’s own dedicated post; calling PowerShell scripts from a batch file.

Why call my PowerShell script from a batch file?

When I am writing a script for other people to use (in my organization, or for the general public) or even for myself sometimes, I will often include a simple batch file (i.e. *.bat or *.cmd file) that just simply calls my PowerShell script and then exits. I do this because even though PowerShell is awesome, not everybody knows what it is or how to use it; non-technical folks obviously, but even many of the technical folks in our organization have never used PowerShell.

Let’s list the problems with sending somebody the PowerShell script alone; The first two points below are hurdles that every user stumbles over the first time they encounter PowerShell (they are there for security purposes):

  1. When you double-click a PowerShell script (*.ps1 file) the default action is often to open it up in an editor, not to run it (you can change this for your PC).
  2. When you do figure out you need to right-click the .ps1 file and choose Open With –> Windows PowerShell to run the script, it will fail with a warning saying that the execution policy is currently configured to not allow scripts to be ran.
  3. My script may require admin privileges in order to run correctly, and it can be tricky to run a PowerShell script as admin without going into a PowerShell console and running the script from there, which a lot of people won’t know how to do.
  4. A potential problem that could affect PowerShell Pros is that it’s possible for them to have variables or other settings set in their PowerShell profile that could cause my script to not perform correctly; this is pretty unlikely, but still a possibility.

So imagine you’ve written a PowerShell script that you want your grandma to run (or an HR employee, or an executive, or your teenage daughter, etc.). Do you think they’re going to be able to do it? Maybe, maybe not.

You should be kind to your users and provide a batch file to call your PowerShell script.

The beauty of batch file scripts is that by default the script is ran when it is double-clicked (solves problem #1), and all of the other problems can be overcome by using a few arguments in our batch file.

Ok, I see your point. So how do I call my PowerShell script from a batch file?

First, the code I provide assumes that the batch file and PowerShell script are in the same directory. So if you have a PowerShell script called “MyPowerShellScript.ps1” and a batch file called “RunMyPowerShellScript.cmd”, this is what the batch file would contain:

SET ThisScriptsDirectory=%~dp0
SET PowerShellScriptPath=%ThisScriptsDirectory%MyPowerShellScript.ps1
PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& '%PowerShellScriptPath%'";

Line 1 just prevents the contents of the batch file from being printed to the command prompt (so it’s optional). Line 2 gets the directory that the batch file is in. Line 3 just appends the PowerShell script filename to the script directory to get the full path to the PowerShell script file, so this is the only line you would need to modify; replace MyPowerShellScript.ps1 with your PowerShell script’s filename. The 4th line is the one that actually calls the PowerShell script and contains the magic.

The –NoProfile switch solves problem #4 above, and the –ExecutionPolicy Bypass argument solves problem #2. But that still leaves problem #3 above, right?

Call your PowerShell script from a batch file with Administrative permissions (i.e. Run As Admin)

If your PowerShell script needs to be run as an admin for whatever reason, the 4th line of the batch file will need to change a bit:

SET ThisScriptsDirectory=%~dp0
SET PowerShellScriptPath=%ThisScriptsDirectory%MyPowerShellScript.ps1
PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& {Start-Process PowerShell -ArgumentList '-NoProfile -ExecutionPolicy Bypass -File ""%PowerShellScriptPath%""' -Verb RunAs}";

We can’t call the PowerShell script as admin from the command prompt, but we can from PowerShell; so we essentially start a new PowerShell session, and then have that session call the PowerShell script using the –Verb RunAs argument to specify that the script should be run as an administrator.

And voila, that’s it. Now all anybody has to do to run your PowerShell script is double-click the batch file; something that even your grandma can do (well, hopefully). So will your users really love you for this; well, no. Instead they just won’t be cursing you for sending them a script that they can’t figure out how to run. It’s one of those things that nobody notices until it doesn’t work.

So take the extra 10 seconds to create a batch file and copy/paste the above text into it; it’ll save you time in the long run when you don’t have to repeat to all your users the specific instructions they need to follow to run your PowerShell script.

I typically use this trick for myself too when my script requires admin rights, as it just makes running the script faster and easier.


One more tidbit that I often include at the end of my PowerShell scripts is the following code:

# If running in the console, wait for input before closing.
if ($Host.Name -eq "ConsoleHost")
    Write-Host "Press any key to continue..."
    $Host.UI.RawUI.FlushInputBuffer()   # Make sure buffered input doesn't "press a key" and skip the ReadKey().
    $Host.UI.RawUI.ReadKey("NoEcho,IncludeKeyUp") > $null

This will prompt the user for keyboard input before closing the PowerShell console window. This is useful because it allows users to read any errors that your PowerShell script may have thrown before the window closes, or even just so they can see the “Everything completed successfully” message that your script spits out so they know that it ran correctly. Related side note: you can change your PC to always leave the PowerShell console window open after running a script, if that is your preference.

I hope you find this useful. Feel free to leave comments.

Happy coding!


Several people have left comments asking how to pass parameters into the PowerShell script from the batch file.

Here is how to pass in ordered parameters:

PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& '%PowerShellScriptPath%' 'First Param Value' 'Second Param Value'";

And here is how to pass in named parameters:

PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& '%PowerShellScriptPath%' -Param1Name 'Param 1 Value' -Param2Name 'Param 2 Value'"

And if you are running the admin version of the script, here is how to pass in ordered parameters:

PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& {Start-Process PowerShell -ArgumentList '-NoProfile -ExecutionPolicy Bypass -File """"%PowerShellScriptPath%"""" """"First Param Value"""" """"Second Param Value"""" ' -Verb RunAs}"

And here is how to pass in named parameters:

PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& {Start-Process PowerShell -ArgumentList '-NoProfile -ExecutionPolicy Bypass -File """"%PowerShellScriptPath%"""" -Param1Name """"Param 1 Value"""" -Param2Name """"Param 2 value"""" ' -Verb RunAs}";

And yes, the PowerShell script name and parameters need to be wrapped in 4 double quotes in order to properly handle paths/values with spaces.



@Antonio Bueno You can definitely do that; it’s nice and short :)

For my blog posts I try to make things more generalized and easy to understand, as not everybody has the same background knowledge. I would rather have a few clear lines over a confusing one liner. Also, your solution has the additional constraint of requiring the .cmd and .ps1 files to have the same name, which some people may not want.

Thanks for the tip though!


Thank you it perfectly works. But I have one question I would like to pass some values into power shell script. I would like to call:

SET PowerShellScriptPath=%ThisScriptsDirectory%MyPowerShellScript.ps1 %1 %2

but it does not work. Please can you provide what is the syntax when I am using parameters inside of BAT or Shall script.

Thank you. Tomas


@Tomas You just need to add the parameters in the last line that actually calls PowerShell, so it would be:

PowerShell -NoProfile -ExecutionPolicy Bypass -Command “& ‘%PowerShellScriptPath%’ ‘%1’ ‘%2’”

or if you want to use the named powershell parameters (instead of ordered):

PowerShell -NoProfile -ExecutionPolicy Bypass -Command “& ‘%PowerShellScriptPath%’ -Param1Name ‘%1’ -Param2Name ‘%2’”


@deadlydog Let me start off by saying this is what I have been looking for, thank you so much for documenting it!

What about passing values with Administrative permissions? I tried using the following an get an error. PowerShell -NoProfile -ExecutionPolicy Bypass -Command “” Basically I need to pass the current directory that the script was called from because I have other scripts that need to be called from that same directory.

Thank You!


Thanks for the good info. I am running a simpler one-liner, from inside a batch file. (Intended to ‘simply’ erase *.xxx files recursively, like “erase *.xxx /s /q”, but without legacy 8.3 issues deleting extra files like *.xxxxx , as per http://support.microsoft.com/kb/164351/en-us; note that Powershell’s remove-item cmdlet still doesn’t work with its -recurse parameter, even in PS 4.0! This is getting crazy complex for something so simple.)

This works from within a batch file:

PowerShell “& Get-ChildItem * -Include *.xxx -Recurse Remove-Item”

But when I try to add parameter -force to right side, to remove hidden files, this does NOT work:

PowerShell “& Get-ChildItem * -Include *.xxx -Recurse Remove-Item -force” [fails]

Any ideas how to get that to work – pipelining with a parameter, on a single line in a batch file?


@Screwuphead Thanks, I’m glad my article could be of help :)

Bringing up a PowerShell command prompt and typing “powershell /?” tells me that you simply provide any parameters you want passed to the script in the -File parameter after the file path. So it will look similar to passing values when not running as admin, as I showed in my comment above to Tomas.

Here is an example of passing extra values into the script when running it as admin: PowerShell -NoProfile -ExecutionPolicy Bypass -Command “& {Start-Process PowerShell -ArgumentList ‘-NoProfile -ExecutionPolicy Bypass -File ““%PowerShellScriptPath%”” -Param1Name ““param 1 Value”” -Param2Name ““param 2 value””’ -Verb RunAs}”

or for your specific scenario of passing in the current directory (here I assume the first/only parameter your script takes in is the directory path, as I’m not passing the value in using named parameters as I do above): PowerShell -NoProfile -ExecutionPolicy Bypass -Command “& {Start-Process PowerShell -ArgumentList ‘-NoProfile -ExecutionPolicy Bypass -File ““%PowerShellScriptPath%”” ““%ThisScriptsDirectory%””’ -Verb RunAs}”


@Jon I don’t know what you mean when you say it doesn’t work (fails); does it give an error message? or simply just not delete the files? I’m guessing that it just doesn’t delete the files, and that you simply need to also provide the -Force switch to Get-ChildItem, otherwise hidden and read-only files won’t be found and passed to the Remove-Item cmdlet. So basically you want to use this:

PowerShell “& Get-ChildItem * -Include *.xxx -Recurse -Force Remove-Item -Force”

I hope that helps. If you still need an answer I suggest posting your question with more detail on Stack Overflow or the PowerShell.org forums, as there are many others there who are smarter than I who can likely help you out :)



Thanks, deadlydog! I missed that -force was needed on Get-ChildItem, as I am new to PowerShell. That did the trick. [Perhaps my comment thread should be removed, as non-pertinent.]


Hello Daniel!

You script to run the powershell works perfect, but I think I have something wrong in my powershell code, that maybe you can help me with. I got it from a person on stack overflow.

Here it is:

if ($(Get-Item C:\Temp\test\test.log).CreationTime -gt [DateTime]::Today) { Write-Host “File Changed at $(Get-Item C:\Temp\test\test.log).CreationTime” } else { Write-Host “File not changed” }

It’s supposed to ceck on test.log, and if that file has changed during the day is shoud display the time of the change and if it has not ben changed during the day it should display: File not changed.

The problem is that it’s always display “File not changed” even if the file has been changed.

Hope you have the time to look at it :)



@Tomas Hey Tomas, this is a little off topic :P but it looks like you just have some syntax issues with the $ symbol. This works for me:

$path = “C:\Temp\test\test.log” if ((Get-Item $path).CreationTime -gt [DateTime]::Today) { Write-Host “File Changed at $((Get-Item $path).CreationTime)” } else { Write-Host “File not changed today” }


This is great for situations where the batch file and powershell script are in the same location. Is it possible to get the batch file location from within the powershell script? i.e. - for situations where the batch file is executing a powershell script located on a network share but you want to write back to the batch file location.


@gm You could always pass in the batch file location as a parameter to the PowerShell script (see above comments for how to pass a parameter to the PowerShell script). To get the running batch file’s path use “%~dpnx0” (without the quotes). If the batch file and PowerShell script are on different computers though (e.g. on network shares), you will want to pass in the batch file location relative to the network share (i.e. instead of passing “C:\MySharedFiles\MyBatchFile.cmd” (which is what %~dpnx0 will give you) to the PowerShell script, pass in “\YourPCsName\MySharedFiles\MyBatchFile.cmd”). It’s easy enough to hard-code that file path in your batch file; I’m not sure how to get it dynamically in batch file code though (fairly easy to do in PowerShell), but I’m sure Google could help you with that. I hope that helps.


I’ve googled and I can’t seem to get a hit for my situation. $Myinvocation doesn’t provide info on the cmd file. Is there something else?


@SB Yup, just add “-WindowStyle Hidden” at the start of the PowerShell argument list to have the PowerShell window hidden while it runs:

PowerShell -WindowStyle Hidden -NoProfile -ExecutionPolicy Bypass -Command “& ‘%PowerShellScriptPath%’”

– EDIT – Actually, it looks like using -WindowStyle Hidden may sometimes still cause the window to show for a split second, because that argument is not evaluated until after the window is open (http://social.technet.microsoft.com/Forums/windowsserver/en-US/783ae81a-15d6-4dea-b283-f0020313c7f0/running-hidden-power-shell?forum=winserverpowershell).


@deadlydog Thanks a lot!

I do have an issue when executing the following command:

PowerShell -NoProfile -ExecutionPolicy Bypass -Command “”

It views all the remaining parameters as a part of -File parameter’s value. Any idea on what I’m doing wrong?


@Amel I’m guessing the blog comments stipped some of your code out here? That line you posted won’t do anything because you haven’t specified a command for PowerShell to execute (i.e. there’s nothing in the double quotes).


@deadlydog That’s what I was afraid of. I tried that and get some type of error that happens so fast I cannot grab it. If I do not run it as administrator it runs okay but that defeats what I am going for. Still hitting my head on the desk to figure out the answer.


@Screwuphead Sorry, I guess I didn’t test it in a path that has spaces, so I never noticed this problem :P

I re-tested and by using the PrintScreen button and GreenShot I was quickly able to see this error:

Processing -File ‘C:\temp folder\Test.ps1 C:\temp folder’ failed: The given path’s format is not supported. Specify a valid path for the -File parameter.

The problem was the powershell script name and each of the parameters needs to be wrapped in 4 (yes 4) double quotes. I’ve updated the code on the post to fix this.



I tried following your tutorial : @ECHO off SET ThisScriptsDirectory=%~dp0 SET PowerShellScriptPath=%ThisScriptsDirectory%SQL.ps1 PowerShell -NoProfile -ExecutionPolicy Bypass -Command “”; pause

but i always get: Missing expression after unary operator ‘-‘. At line:1 char:2

  • -E <<<< xecutionPolicy Bypass -Command

any help?



Anyone knows how I can execute .cmd from powershell. I try this but doesnt work

Invoke-item C:\setup.cmd -ArgumentsList /c -install-setupforced

Really appreciate your help


Hi, great post - I’m a bit of a newbie to PS, but I can’t get the ‘wait’ clause to work…if I run your code from within Powershell I get:

PS E:\Data\Scripts\Powershell> # Wait for input before closing. Write-Host “Press any key to continue…” $x = $Host.UI.RawUI.ReadKey(“NoEcho,IncludeKeyUp”) Press any key to continue… Exception calling “ReadKey” with “1” argument(s): “The method or operation is not implemented.” At line:3 char:1

  • $x = $Host.UI.RawUI.ReadKey(“NoEcho,IncludeKeyUp”)
  • ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    • CategoryInfo : NotSpecified: (:) [], MethodInvocationException
    • FullyQualifiedErrorId : NotImplementedException

Other Googling seems to suggest I can’t use ReadKey with PS?

Any pointers would be most appreciated.


@Tim Sorry, that code will throw an exception if you are not running your script from the PowerShell Console; I’ve updated it to wrap it in an IF statement so it only prompts for input when running in the PowerShell Console.

If you want to prompt for input before continuing regardless of which host the script is running in (e.g. PowerShell ISE), then you can use:

Read-Host -Prompt “Press Enter to continue…” > $null

The difference here though is that the user must press Enter to continue, not just any key.


Very good post. The problem is that we have a mapped drive (S:) that we use for scripts/software installs for IT folks so when you use “-verb RunAs” in the CMD file and use an elevated domain account , you get an error presumably because there is no mapped S: drive for that elevated account. If you hard code the UNC path it works, but would not like to do that.

Something like this may work if it is incorporated somehow? Any ideas? http://superuser.com/questions/29933/get-the-current-unc-path-from-a-local-path-in-powershell


@rcf Unfortunately I don’t have much experience using network drives in my PowerShell scripts :(

Why don’t you want to hard code the UNC path? You just don’t want the user to see the full UNC path (e.g. \SomeServer\SomeFolder\SomeOtherFolder\ScriptsFolder) for security reasons? Or you are afraid that if the UNC path ever changes that it will break all your scripts? One possible workaround may be to create another “shortcut” UNC path that simply points to the real UNC path (e.g. \Shortcuts\ScriptsFolder). This would both hide the absolute UNC path from the user, and you could always change the shortcut UNC path to point somewhere else if needed. I don’t know the proper terms for this or how to set this up myself, but I know at my organization we have several different UNC paths that all point to the same network location, so I’m sure it’s possible to do.

I hope that helps.


Thanks for the insight. We use a generic ‘install.cmd’ wrapper for all of our installs so it would really be nice to be able to use one standard script for everything that detects the current path if run from a mapped drive - no modifications wherever it is run from. The other reason that you mentioned is also a concern - that the script will break if the UNC path changes if hard coded. I think I’m close at getting it going based on the link in the previous post. It seems to detect the UNC path from a mapped drive nicely. This would cover us if the script was run from a mapped drive or not.


Great article!

You mention how to pass variables into powershell from the .bat files. Would you know how to go the other way and pull out exit codes or variables from the powershell script? If say for instance you wanted to show if the PS script ran successfully from the .bat file?


@Charles Google and Stack Overflow are your friend ;)

To read the last running program/scripts exit code, use the ERRORLEVEL variable as they show here: http://stackoverflow.com/questions/334879/how-do-i-get-the-application-exit-code-from-a-windows-command-line

To have your PowerShell script return an exit code (other than zero), be sure to have the script exit using:

exit [some integer]

To pull some variable’s value from PowerShell into the batch script I think you would need to write the value in PowerShell using Write-Output, and then capture that output somehow, perhaps by using stream redirection, http://technet.microsoft.com/en-us/library/bb490982.aspx.

Sorry I don’t have all of the answers, but I hope this helps.


I’m trying to do something similar but having problems. For ease of use for the users that will be runnning this I want the commands to be in a batch file. I need to create some AD security groups but need to specify the OU to use and the group name in the variables. The user running the script will enter the branch code and OU and the group will be built off those values. Here is what I have so far but I think the space in the group name is causing problems. It seems to think that “Test” is another parameter. I have tried enclosing the name value in double parenthesis but its still gettng the same result.

Any suggestions?

SET /P OU=Enter OU: Set /P Prefix=Enter Prefix: Powershell New-ADGroup -Name “%Prefix%-OWA Test” -SamAccountName “%Prefix%-OWA Test” -GroupCategory Security -GroupScope Global -path “OU=%OU%,OU=Test1,DC=Test2,DC=Test3,DC=Test4,DC=com”


@Mike This problem is slightly off-topic and better suited for Stack Overflow, as it is more along the lines of “how to execute PowerShell code from within a batch file”, but I’ll take a whack at it. Just from looking at what you have here, the problem is likely that you need to pass your PowerShell command via the actual -Command switch, so something like this:

Powershell -Command {New-ADGroup -Name “%Prefix%-OWA Test” -SamAccountName “%Prefix%-OWA Test” -GroupCategory Security -GroupScope Global -path “OU=%OU%,OU=Test1,DC=Test2,DC=Test3,DC=Test4,DC=com”}

From the command prompt just type “PowerShell /?” to get more info on passing parameters to the PowerShell.exe executable.

Or a hackier way might be to do something like this, which starts up a new powershell session then simulates you typing the command into the console and hitting enter:

ECHO New-ADGroup -Name “%Prefix%-OWA Test” -SamAccountName “%Prefix%-OWA Test” -GroupCategory Security -GroupScope Global -path “OU=%OU%,OU=Test1,DC=Test2,DC=Test3,DC=Test4,DC=com” PowerShell

I hope one of those solutions works for you.


@deadlydog Thanks for the reply. I’ll take your advice and post on Stack Overflow.

I tried both suggestions and they don’t error out but they don’t create the groups either so I’m not sure what is going on. When I run them, it just echoes the command back to me. I also never see the Active Directory Module being loaded. I think it has something to do with the curly braces because when I remove them the AD Module loads but I get the error shown below. I just started learning about Powershell so I’m still not clear on the specifics of when to use {,”,’,or[. I also tried running the command directly without using the variables in my post above but get the same error. Its something related to running from the cmd line though as I can run it in powershell succesfully. Here is the error I get when I run without the curly braces. New-ADGroup : Cannot convert ‘System.Object[]’ to the type ‘System.String’ required by parameter ‘Path’. Specified method is not supported. At line:1 char:110

When running the admin version of the script with named parameters, if my parameters are argumnts to the batch script, then I end up having incorrect argument parsing on the PS1 side when the arguments are empty.

E.g. P.BAT: PowerShell ….. -P1 “””“%1”””” …

P.PS1 param([string]$P1) Write-Host -$P1-

Running P.BAT results in -“-

Any idea how to protect against that ?


I have been using deleteold.ps1 from Technet http://gallery.technet.microsoft.com/Powershell-script-to-ed34c5f9 to clear up files older than x days on individual nodes in our HPC Cluster. From the headnode I use it with the following parameters .\deleteold.ps1 -FolderPath \Nodename1\c$\project-9\input-data\temp -FileAge 7 -LogFile Nodename1.log

The powershell script is on a network share that the headnode and all computenodes can see and write to.

Jobs being run by users create hundreds of files so the clean up can take 15min to 1 hour depending on what else is happening on the node at the time.

I would like to run the from the Clusrun command line in the ClusterManager so that it can process the task simultaneously rather than sequentailly as at present. Obviously I modify the -Folderpath parameter to only have the c$\project-9\input-data\temp but I cannot work out how get it to run either directly or via a batch file.

Can anybody help please?


@GlwDay A couple ideas: 1 - Use a remote session to delete files, so the commands run directly from the remote maching. i.e. New-PSSession -ComputerName $Server 2 - To make them run in parallel, use several Start-Job commands to call your script, and instead of passing in the root directory, pass in folders in the root directory. i.e. Start-Job .\deleteold.ps1 -FolderPath \Nodename1\c$\project-9\input-data\temp\Folder1 -FileAge 7 -LogFile Nodename1.log Start-Job .\deleteold.ps1 -FolderPath \Nodename1\c$\project-9\input-data\temp\Folder2 -FileAge 7 -LogFile Nodename2.log …


@deadlydog Hi i have the same issue i need to create user in active directory from batch files by calling script can u provide any workaround for this problem, am new to this power shell.


In the “run as admin” version, when passing parameters, and when the powershell script is passed as an environment variable, the -File parameter does not want any doublequotes, neither 2, nor 4. In other terms, of these three -File “””“%myScript%”””” -Param1name “”"”Param 1 value”””” -Param2name “”"”Param 2 value”””” -File ““%myScript%”” -Param1name “”"”Param 1 value”””” -Param2name “”"”Param 2 value”””” -File %myScript% -Param1name “”"”Param 1 value”””” -Param2name “”"”Param 2 value”””” only the third one works. This probably solves Jerome’s issue. @Jerome Lacoste


Oh by the way, deadlydog: You ROCK! A caveat, though: under IE11 (whether in compatibility mode or not) the last line of the code snippets is not visible (nor can it be cut’n’pasted). As a consequence, one-line snippets are not visible at all! One has to view the HTML source, but HTML escaping makes it awkward to reproduce the correct source code. I don’t know if you can fix that, but just in case…



Thank you for the code. It’s exactly what i am looking for. But i just can’t get it working: SET “InstallerFolder=\dc01\e”

PowerShell -NoProfile -ExecutionPolicy Bypass -Command “”;

Should this not work? The script runs and all is good, but it is not running as administrator :(

Thank you.


Very helpful page.

One issue i had; if your script raises a Windows credential dialog (eg. Add-Computer) then key presses appear to get buffered and can skip through the “Press any key to continue…” code.

This resolved the issue for me.

$Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyUp') &gt; $null

Great Article. I have a tab delimited text file which contains values my bat file will read and pass to the PowerShell script, this is so I can have multiple lines in the input file so can do multiple. The bat file does the following: FOR /F “tokens=1-1” %%i in (C:\Values.txt) do PowerShell -NoProfile -ExecutionPolicy Bypass -Command “”;

The test.ps1 is a simple test file which should print Item1 (which needs to have come from the %%1 substituted value):


$text = $Item1 $text | Set-Content ‘C:\file.txt’

In my test file I get the word Parameter rather than the word contained in my values.txt file - not sure how I go about construction the -commend “” section so that %%i can be used/substituted. Anyone done this before?

Any help appreciated


Hello, I’m a noob so please bear with me. I ave a batch file that calls a ps1. The ps1 seems to run, the last thing it does is creates a log file which indicates that all tasks have bee completed. The problem is that it nevers passes control back to the batch file. Even inputing an exit command after the logging sections does not help. any ideas?


@noobie Does the PowerShell window exit? I’m guessing that your logging functionality is actually a blocking call and never completes (it waits for something else to happen), so execution is stuck there. I would try asking on StackOverflow with a code example to get an answer if you are still stuck.

So I found a problem, when running the powershell script with Administrative permissions (i.e. Run As Admin), it will not wait for user input at the end of the script. Placing -NoExit as part of the argument list works, but then quite obviously after the you press any queue, Powershell does not exit. :) If I run my script without Administrative permissions, then the code you provided above will wait for user input. My question is, how do I get this to work with Administraive permissions? It is useful to be able to capture error messages (if any).


I tried this code in .cmd @ECHO OFF SET ThisScriptsDirectory=%~dp0 SET PowerShellScriptPath=%ThisScriptsDirectory%IIS_Restart.ps1

PowerShell -NoProfile -ExecutionPolicy Bypass -Command “”;

and below in .ps1 file

sleep 50

Write-OutPut “Restarting IIS”


but still its not working it says “ u need admin access”, can some one help me how can i run powershell script as an admin


@Allen Did you read this blog post? I give the code for how to run the script as admin just a few lines below the code that you are using for how to run it normally; just use that Run As Admin method instead to call your PowerShell script:

PowerShell -NoProfile -ExecutionPolicy Bypass -Command “& {Start-Process PowerShell -ArgumentList ‘-NoProfile -ExecutionPolicy Bypass -File ““%PowerShellScriptPath%””’ -Verb RunAs}”;


Thank you for update, I used same code what you gave

@ECHO OFF SET ThisScriptsDirectory=%~dp0 SET PowerShellScriptPath=%ThisScriptsDirectory%IIS_Restart.ps1

PowerShell -NoProfile -ExecutionPolicy Bypass -Command “”;

I am getting error as below

Access denied, you must be administrator of the remote computer to use this command. either add your account to administrator local group of remote computer or to domain administrator global group.

I am already admin on that remote computer. still i am getting same error every time.

David Wohlberg

@Allen @Allen, as @deadlydog already pointed out, you need to add “-Verb RunAs” without the quotes to your call to launch Powershell, otherwise it is is just running in normal mode, not adminstrative mode.

Sandeep Saxena

I am using below on the similar lines :

  1. echo %VM_Name%
  2. @ECHO OFF
  3. SET ThisScriptsDirectory=%~dp0
  4. SET PowerShellScriptPath=%ThisScriptsDirectory%Test.ps1
  5. PowerShell -NoProfile -ExecutionPolicy Bypass -Command “”;

Line number 1 is working and variable %VM_Name% is echoed. But in line 5 -VM_Name “””“%VM_Name%”””” is not working. I am using variable $VM_Name in my Test.ps1 and powershell says that this variable is null.

In line 5 I am trying to pass a parameter like this : Start-Process PowerShell -ArgumentList ‘-NoProfile -ExecutionPolicy Bypass -File “””“%PowerShellScriptPath%”””” -VM_Name2 “””” %VM_Name2% “””” ‘ -Verb RunAs


Hello there,

Very good idea!

However, when running the bat file, instead of executing the script the command open the script in Notepad. Any ideas?

If I removed the single Quotation mark ‘ ‘ from “& %PowerShellScriptPath%”, the script get executed, but if the file path have any space with the folder, it will resulted in error. Eg S:\Repairs and Backup\test.ps1 will throw an error.



I’m trying to run a powershell command from the command line where I want to use the ‘pipeline’ “|” It fails on the command line, but it runs oke witin a powershell environment.

How can I use the “ ” on a commandline powershell command?

F:\OTA\scripts>Powershell.exe -ExecutionPolicy RemoteSigned -File F:\OTA\scripts\GetGroups.ps1 SwartJ | Export-CSV .\NedstedMembers_SwartJ.csv -NoTypeInformation ‘Export-CSV’ is not recognized as an internal or external command, operable program or batch file.

When I use the next command I only get a powershell command prompt. Powershell.exe & “-ExecutionPolicy RemoteSigned -File F:\OTA\scripts\GetGroups.ps1 SwartJ | Export-CSV .\NedstedMembers_SwartJ.csv -NoTypeInformation”


Great. I find however embedding Powershell in a DOS batch cleaner http://stackoverflow.com/questions/2609985/how-to-run-a-powershell-script-within-a-dos-batch-file


Thanks for the batch help! I’m getting an error that somehow a space is being inserted in the path. Batch file: SET ThisScriptsDirectory=%~dp0 SET PowerShellScriptPath=%ThisScriptsDirectory%Delta.ps1 PowerShell -NoProfile -ExecutionPolicy Bypass -Command “& ‘%PowerShellScriptPath%’”; Error: & : The term ‘C:\PSLib\ Delta.ps1 ‘ is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. There is not a space in the filename. Any clues?


Someone can help me? I am trying to run one powershell script from a batch file just to create a txt file with the list of the software installed on the computer, but it does not work. The batch file contains: @echo off PowerShell -ExecutionPolicy Bypass -Command “& ‘%~dp0’”; PAUSE The powershell script file which has the same name as the batch file simply contains: Get -WmiObject -Class Win32_Product C:\software.txt

Daniel, You are so wonderful to post this fantastic information! Thank you! I Googled many, many, many, MANY articles, but YOURS did the trick! I was able to understand it and do it and make my boss happy.

I created batch files (using your instruction) that stop and start a Windows service. These were used in an InstallShield Basic MSI project. I created Custom Actions that called InstallScripts, that called the batch files, that called Powershell scripts (with Admin privileges) to stop and start the service before and after the install.

Thanks again, and I hope you will keep posting!



Great Article!

Just one question:

I am using the named parameter admin solution that you showed how to pass variables. The issue that I’m having is that one of my parameters takes an array of strings. I can pass it from the command line no problem. but when I pass the same thing inside 4 double quotes as you showed. It does not parse it correctly.

Is there a piece I’m missing to pass an array?


Hi Could someone help me.. I am trying to schedule a bat file which is calling Power shell in Task scheduler and schtasks but my bat file is getting executed and when it calls powersell it’s not getting executed. What could be the reason. How should I schedule a bat file which calls power shell.


Thank you for putting so much time into this blog. It is very helpful. I am coming across a problem and I am letting you know now I am a noob when it comes to this. I have the following PowerShell script and it runs perfectly if I type it directly in PowerShell… CD C:\Temp Get-ChildItem -Filter “-Layout1” -Recurse | Rename-Item -NewName {$_.name -replace ‘-Layout1’,’’ }

When I run it thru a .bat I get the following error…

“You must provide a value expression on the right-hand side of the ‘-replace’ oerator. At C:\Users\Desktop\PowerShell\MyFileRenameUtility.ps1:3 char:85 Get-ChildItem -Filter “-Layout1” -Recurse | Rename-Item -NewName {$_.name -replace <<<< a?~Layout1a?T,' ' }

I don't understand how PowerSheel recognizes the commands but then doesn't recognize them. Do you have any suggestions?


@Christopher Basically I am using this because our CADD program adds “-Layout1” or “-Model1” to the file name of each output file. I sometimes have hundreds of these files, each with a different name but they all have “-Layout1” or “-Model1” in common. I can use the script directly in PowerShell and it runs perfectly. Just getting over that hump of passing it from the batch file for other users to use it as well.


Old post - if anybody has any input, the PS1 I’m trying to run must be ran on a domain controller. I have a little program I made (Filemaker) that I import powershell scripts, then use the batch coding from this site which is created on the fly from the program to invoke the PS1,,, but, the PS1 for this one script must be ran from the DC,,, I was thinking that instead of rebuilding the PS1, there has to be a way of initiating the PS1 to run from the perspective of it’s current computer host location

… in other words, I set the location of the PS1 and batch script to export from my program onto the target computer (a domain controller in this case), and execute it,,, but it’s execution ‘perspective’ is from the computer it is executed from, not the computer it is stored on,,, make sense?

Steven Stover

Quote: And yes, the PowerShell script name and parameters need to be wrapped in 4 double quotes in order to properly handle paths/values with spaces.

This fails when the parameter ends with a backslash character, c:\ would be passed as c:” with a double quote replacing the backslash.


Hi i am trying to run as you mentioned here in the below lines replacing script wtih my PS script but its still prompting for UAC and doesn’t proceed without asking for it when scheduled it as task with system user as this is the way i want it run, i ran some .bat files which needs admin permissions and those works fine. but the same .bat file when run it from admin cmd prompt it works, i @ECHO OFF SET ThisScriptsDirectory=%~dp0 SET PowerShellScriptPath=%ThisScriptsDirectory%MyPowerShellScript.ps1 PowerShell -NoProfile -ExecutionPolicy Bypass -Command “”;

Let me know what i am missing here


I’m running into a problem, trying to have this batch file start my script but nothing happens I need to run this as admin since the execution policy will be set to restricted by default. Do you guys have any idea what is wrong with my code? Thanks.

@ECHO OFF SET ThisScriptsDirectory= %~dp0 SET PowerShellScriptPath= %ThisScriptDirectory%NameOfMyScript.ps1 PowerShell -NoProfile -ExecutionPolicy Bypass -Command “”

David Wohlberg


Take a look at the two examples provided in the blog above, you’re not passing your %PowerShellScriptPath% variable, you just have empty quotes.

Budd McNish

I have tried all variations of executing a PS1 from a .BAT file that passes a single parameter to the PS1. UNSUCCESSFULLY !!!

sample1:PowerShell.exe -NoProfile -ExecutionPolicy Bypass -Command “& ‘my.ps1’ -sfn’%1%’”;

sample2: PowerShell.exe -NoProfile -ExecutionPolicy Bypass -Command “& ‘my.ps1’ ‘%1’”;

Always the same result: Now: 02/23/2017 14:01:57 : filename = Now: 02/23/2017 14:01:57 : input filename is missing, run aborted


Hi..I am trying to create a batch file to start/stop clusters on a remote server through a powershell script but I keep getting an error that the cmdlet does not exist


@ECHO OFF SET ThisScriptsDirectory=%~dp0 SET PowerShellScriptPath=%ThisScriptsDirectory%Start-ClusterGroup.ps1 PowerShell -NoProfile -ExecutionPolicy Bypass -Command “& {Start-Process PowerShell -ArgumentList ‘-NoProfile -ExecutionPolicy Bypass -File ““%PowerShellScriptPath%””’ -Verb RunAs}” ———————————————————————————————— Start-ClusterGroup.ps1 ————————-

Start-ClusterGroup -Name ‘$ClusterGroupName’

Both these files are saved in the same location but when I run the batch file,it does prompt for me to enter the ClusterGroupName but on doing so,get the following error :-

The term ‘Start-ClusterGroup’ is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. At C:\Intel\script\Start-ClusterGroup.ps1:18 char:19

  • Start-ClusterGroup <<<< -Name '$ClusterGroupName'
    • CategoryInfo : ObjectNotFound: (Start-ClusterGroup:String) [], CommandNotFoundException
    • FullyQualifiedErrorId : CommandNotFoundException

I did an import-module failoverclusters as well but that doesn't seem to help either.Could you please tell me what is it that I am doing wrong?



@Shweta It looks to be a problem with your PowerShell script itself. I assume you get the error just when running the PowerShell script without using the batch file? I would post your question along with some code on StackOverflow.com to see if anybody can help you out.


Hello, thanks for the explanation. I appreciate it. FYI, I did run into a problem because I needed to add “setlocal enabledelayedexpansion” to my batch file before it would work as shown.


Hi I have a question, I’m receiving the following error when tryyig run the batch file:

Original Batch File: AppxPackagePowershell.bat @ECHO OFF SET ThisScriptsDirectory=%~dp0 SET PowerShellScriptPath=%ThisScriptsDirectory%AppxPackage.ps1 PowerShell -NoProfile -ExecutionPolicy Bypass -Command “& ‘%PowerShellScriptPath%’“;PowerShell -NoProfile -ExecutionPolicy Bypass -Command “& {Start-Process PowerShell -ArgumentList ‘-NoProfile -ExecutionPolicy Bypass -File ““%PowerShellScriptPath%””’ -Verb RunAs}”;

Both files are in the C:\Windows\Setup\Scripts directory as directed in your instructions

Hi Folks,

The script seems to think there is a space between the directory and the file

coded SET PowerShellScriptPath=%ThisScriptsDirectory%Script.ps1

feedback in the DOS screen (when I run it) suggests this c:\powershell\spaceScript.ps1

Have I coded this wrong?

I’m sure its something silly I’ve done

Thanks, Andrew

David Wohlberg

@Andrew Would be helpful to see how you set the variable %ThisScriptsDirectory%

My guess is you have a space at the end after %~dp0. The cmd interpreter simply thinks you wanted that space as part of your path that you were trying to set.

David Wohlberg

@HighwayCO (Don) If you look closer at your command, just before %PowerShellScriptPath% you are using some other character that is not a single quote. Perhaps it copied wrong when pasting it in this blog, but I suspect it is wrong in your source. Also your double quote characters are questionable as well. Using something like Notepad.exe (I prefer better text editors myself, like Notepad++), when I copy your script and paste it into either of these editors you’ll see the quote characters are not formatted properly. My non-caffeinated brain at the moment can’t think of the proper term for the quote characters you want, but they literally look like plain chicken scratches, and not the better formed curly type you might expect in a document processor like MS Word.

Replace all your double quotes and single quotes in your original script with proper plain text quote characters and I suspect your errors will go away.


@echo off SET thisScriptsDirectory=%~dp0 SET thisScriptsDirectory_ohneSlash=%thisScriptsDirectory:~0,-1% powershell -NoProfile -ExecutionPolicy Bypass -Command “& {& ‘%thisScriptsDirectory_ohneSlash%\GUI.ps1’ -N ‘parameter string’}”


Hi deadlydog, I have some batch files I am where I execute powershell.exe -NoProfile -ExecutionPolicy Bypass -Command “.\script.ps1”. What is the difference with -Command “script.ps1” and -Command “& {.\script.ps1}”?


@arkiados This post (http://www.itprotoday.com/management-mobility/running-executables-powershell) describes it in more detail, but essentially if the file path has a space in it, the & syntax is required; not using it would result in an error being thrown instead of the script being ran.


@deadlydog Thanks for the quick reply. I have a situation where a proprietary app calls cmd.exe which runs a batch file that calls powershell.exe -NonInteractive -NoProfile -ExecutionPolicy Bypass -Command “.\script.ps1”. script.ps1 does a $host.setshouldexit($exitcode) and then Exit. The batch file has an Exit. But for some reason the powershell.exe process doesn’t exit. The real annoyance is that all of this works just fine if I manually fire up cmd.exe, open another cmd.exe to replicate the proprietary app doing it, and execute the batch file that calls powershell.exe. I think now that this issue is outside of the scope of your post but maybe you know something that could help.


@arkiados I’m not certain about the issue your describing. I found this StackOverflow post that looks related and may help you out (https://stackoverflow.com/a/35492775/602585). If that doesn’t help you solve it, I’d recommend posting on StackOverflow as the community is awesome and vast and can likely help you solve it.

Your legacy lives on! This came in so handy and I see that is true for so many others through many years! Thank you!


Hello. I am following your example of calling PowerShell from PowerShell to use -Verb RunAs. When the second Powershell starts, I get a dialog box that asks “Do you want to allow this app to make changes to your device?” - Windows Power Shell. I have to hit Yes or No. I am an admin on this PC but I want my users to run this who are not admins. Is there anyway to suppress that dialog for admins and non-admins?


I am wondering if using the batch file approach, can you run one PS script and keep open the shell. then run via batch file another PS in the same shell.

What I am trying to do is open a serial port (and keep it open) then call a second script from a batch file with attached parameter to send some data out of the serial port. As I understand it there is no way to send parameters to a running script, and when calling from a batch file a new instance of Powershell opens and is not using the same environment as the first.

I have a software PVR that will launch a program in windows to change channels, it appends parameter to the command line. I have an arduino on the serial port that can change the channel on the set-top box. But I can’t find a clean solution to make the communications work well. The arduino must have the port opened before recieving the channel data.

Any comments or suggestions would be very helpful.

David Wohlberg

@Mike Perhaps someone will have a better solution, but if I were in your shoes, I would probably try to make use of a file to pass the parameter/data to. The PS script that you use to keep the serial port open would need to periodically read from this file. Your second script would then write the necessary data to that file.


How do I format this correctly so that Powershell reads recognizes the $env: and the (get-date)?

This is like the 3rd step in two bath files I have that help trigger an Automated Windows Server Backup check when a backup completes. It’s supposed to grab a screenshot and format it as COMPUTERNAME_DDMMYY.png so a later script can attach it to a Send-MailMessage.

I just can’t figure out how to feed the script those arguments from a batch file.

SET ScriptDir=%~dp0 SET PSSPath=%ScriptDir%Take-Screenshot.ps1 powershell -NoProfile -ExecutionPolicy Bypass -Command “& {%PSSPath% -activewindow -file “C:\TN\Scripts\WBA\ScreenShots$env:computername_(get-date -F ddMMyy).png” -imagetype png}”



Need help.. My command is working fine in Powershell.. I want to run the same by creating batch(.bat). here is the command C:\Users\sysname\Desktop\Debug .\runTest.ps1 -environment staging -configFile ConfigFiles\Part1.xml

How to create a bat file for this

Elie Saab

Dear All

I had a problem concerning the language preference that is adding the uk keyboard by itself and it was resolved manually by entering the powershell and typing the following: Get-WinUserLanguageList $1 = New-WinUserLanguageList en-US Set-WinUserLanguageList $1 and it worked.

what I would like to know how to put these lines in a batch file to run it directly from the desktop because each time I restart my computer I have to do the same steps again.

thank you in advance

Rob Peterson

Not exactly sure why the batch file isn’t running… the log for the script isn’t created and there isn’t anything in the Event Viewer. Everything runs smoothly when running direct within PowerShell so that part is correct. Here’s the command that I’m running inside PowerShell:

C:\Password_Expiry_Email.ps1 -smtpServer smtp.gmail.com -expireInDays 10 -from “user@domain.com” -Logging $true -LogPath “C:\PasswordExpiryLogs” -testing $true -testRecipient testuser@domain.com

This does have to be run from the active directory module. Here’s what I have been using for the batch file (in some form or another without success):

@ECHO OFF SET ThisScriptsDirectory=%~dp0 SET PowerShellScriptPath=%ThisScriptsDirectory%Password_Expiry_Email.ps1 PowerShell -NoProfile -ExecutionPolicy Bypass -Command import-module ActiveDirectory “& {Start-Process PowerShell -ArgumentList ‘-NoProfile -ExecutionPolicy Bypass -File -Command import-module ActiveDirectory “””“%PowerShellScriptPath%”””” -smtpServer “”"”smtp.gmail.com”””” -expireInDays “”"”10”””” -from “”"”user@domain.com”””” -Logging “””“$true”””” -LogPath “”"”C:\PasswordExpiryLogs”””” -testing “””“$true”””” -testRecipient “”"”testuser@domain.com””””’ -Verb RunAs}”;

Amina Faruqi

Hi @deadlydog, First of all thank you so much for this helpful post! this was EXACTLY what I was looking for!! :). I’ve created my batch file as well as my PS script. I am calling my PS script by passing in parameters and the values

PowerShell -NoProfile -ExecutionPolicy Bypass -Command “& ‘%PowerShellScriptPath%’ -urlPath ‘Value1’ -serviceName ‘Value2’”

and my PS script has the parameters defined like below: param ( [parameter(Mandatory=$true)] [string] $urlPath,

    [string] $serviceName
)  $http = netsh http show urlacl url=$urlPath
if(-not($http -match $serviceName))
    netsh http add urlacl url=$urlPath sddl="D:(A;;GX;;;NS)"
    Write-Host "it's there"
} }

For some reason when I run my batch script, it opens up the command prompt but doesn’t actually register the urls.

Am I passing in the parameters correctly? or is there a way to debug this process? Again, thank you in advance for your assistance. You’ve been a great help so far :)

Tim Nielsen

Dan, just wanted to say thanks for spending the time on this. I really appreciate it. Your explanation is very clear.


Hi, I need to use PSEXEC to launch powershell with a system account and then pass the commands to the new window. I get an exit code of 0, which normally means it’s worked,but when running a command to check, it hasn’t? This is the bat file I’ve written, any advice would be very greatly appreciated!

@echo off .\psexec.exe -i -s PowerShell.exe -command {‘.\Add VPN.ps1 -xmlFilePath .\Device Tunnel VPN Profile_RemovedTrafficFilter.xml -ProfileName Test_Device_VPN’}


Mark Rohren

I wrote the following one-line batch program to convert a PowerShell script to a .bat file. Copy it to a “p2b.bat” file and enter “p2b “ (the .ps1 extension is optional); the output file will be the same prefix with a .bat extension. The output batch program can take parameters or arguments, but is limited to just under 8192 characters. I even used the script to modify itself!

@echo off & powershell -command “&{$dq=[char]34;$hash=[char]35;$pct=[char]37;$amp=[char]38;$sq=[char]39;$sc=[char]59;$lt=[char]60;$gt=[char]62;$bt=[char]96;$strLen=0;$inComment=0;$inSq=0;$inDq=0;$inQuotes=0;$inParens=0;$inSquares=0;$script=$args[0];if($script.length -lt 1){$script=Read-Host "Enter name of script";$pause=1}if(-not($script-match("."))){$script+=".ps1"}$batch=$script-replace "..", "";$batch=$batch+".bat";$lines=Get-Content $script;$str="";foreach($line in $lines){if($line.length -gt 0){if($line-match "$lt#"){if($line-match "#$gt"){$line=$line-replace "(.)$lt#.#$gt(.)", ‘$1$2’}else {$line=$line-replace "$lt#.$", "";$inComment=1}}elseif($line-match "#$gt"){$line=$line-replace "(.)#$gt(.)", ‘$2’;$inComment=0}if($inComment -eq 0){$line=$line-replace "$pct", "$pct$pct";$esc=0;$outLine="";$len=$line.length;$i=0;$prev=’‘;while($i -lt $len){$char=$line[$i++];if($i -eq $len){$next=’‘}else {$next=$line[$i]}if($esc -eq 0){if($inQuotes -eq 1){if(($char -eq $lt)-or($char -eq $gt)-or($char -eq $amp)){$outLine+=’^’}if($inSq -eq 1){if($char -eq $sq){$inSq=0}}elseif($inDq -eq 1){if($char -eq $bt){if($next -eq $dq){$char=$dq;$inDq=0}elseif($next -eq ‘:’){continue}}elseif($char -eq $dq){$inDq=0}}if(($inSq -eq 0)-and($inDq -eq 0)){$inQuotes=0}}else {if($char -eq $hash){break}elseif($char -eq ‘(‘){$inParens+=1}elseif($char -eq ‘)’){$inParens -=1}elseif($char -eq ‘[’){$inSquares+=1}elseif($char -eq ‘]’){$inSquares -=1}elseif($char -eq $sq){$inSq=1;$inQuotes=1}elseif($char -eq $dq){$inDq=1;$inQuotes=1}elseif($char -eq ‘ ‘){if(($prev -like ‘[=)+]’)-or ($next -like ‘[=(+]’)){$char=’’}}}}if($char -eq $dq){$outLine+=’'}if($char -eq ‘\’){$esc=1}else {$esc=0}$outLine+=$char;$prev=$char}$outLine=$outLine.trim();if($strLen -gt 5000 -and -not $outLine-match("^else")-and -not $outLine-match("^]Param")-and -not $outLine-match("^catch")-and -not $outLine-match("^finally")){$strLen=0;$outLine="$dq;$dq$outLine"}if(($inParens -lt 1 -and $inSquares -lt 1 -and $inQuotes -eq 0)-or($outLine-match("$bt$"))){if($outLine.length -gt 1){$outLine+=";"}}$str+=$outLine;$strLen+=$outLine.length}}}$str=$str-replace "$bt;", "";$str=$str-replace ",$sc", ",";$str=$str-replace "$sc{", "{";$str=$str-replace "{$sc", "{";$str=$str-replace "$sc}", "}";$str=$str-replace "]($sc)[Pp]aram", "]param";$str=$str-replace "($sc)[Cc]atch", "catch";$str=$str-replace "($sc)[Ff]inally", "finally";$str=$str-replace "($sc)else", "else";$str="@"+"echo off $amp powershell -command ""$amp{"+$str+"} %%*""";$str Set-Content "$batch";Write-Host "output batch file: $batch";if($pause -eq 1){$pause=Read-Host "Press any key to continue"}} %*”
Mark Rohren

Part of my original post got stripped because of angle brackets; to run the script, enter “p2b” followed by the name of the script you wish to convert, for example “p2b myscript.ps1” (or “p2b myscript”; the .ps1 is optional). Then you can run the script as a batch by entering the script name without the .ps1, as well as any optional arguments, like “myscript myfile.txt 3”.

Thanks for the great blog and post!


Hello kind and clever people.

I need help to run a powershell script in a batch file. I run the powershell script manually every single day and I wanted to automate it if possible with your help. Note that I am renaming a large number of files.

this is the script I ran under the command prompt of powershell

get-childitem TSIL_*.pdf rename-item -NewName {$.name -replace ‘^TSIL’,’’}

the directory is c:\customer\pdf

my target is to remove the first 5 chars of the filename.

input filename : TSIL_12345_111_222.pdf target output : 12345_111_222.pdf

I will greatly, appreciate if you can write the code for me or better if you have other solution that you can assist with.

Thanks you and god bless.

sorry, i’m a noob and have a powershell script that i want a non admin user to be able to double click a batch file to run. i’ve followed the instructions and it works fine for my domain admin account, but two things keep stopping it from working for a non admin account. if i run the ps1 file, it gives me an access denied error. if i run my batch file it asks for admin credentials. i’ve added -Verb RunAs}”; but it’s still not working.

hoping someone can help point me in the right direction!



Barsa Mohapatra

I want to pass multiple arguments into the single parameter while running the PS script from a .bat file , PowerShell -NoProfile -ExecutionPolicy Bypass -Command “& ‘./DW 6.12 Install.ps1’ -modules ‘Printer’ -modules ‘Scanner’ -modules ‘EditSend’ -modules ‘Import’ ‘SmartConnect’ ‘WEC’ ‘IndexCleaner’ ‘UrlCreator’ “

How do I declare the variable in powershell ,its only installing the 1st module not all of them


hi all, in the below code, am saving variable from external file to batch file and i want to pass the variable into power shell

Bat file:

@echo off SetLocal EnableDelayedExpansion set content= for /F “delims=” %%i in (C:\Campaign\cupid\ee.txt) do set content=!content!%%i echo %content% EndLocal pause powershell.exe -ExecutionPolicy Bypass -File C:\sample\cupid\a.ps1 %content% pause



Expand-Archive -LiteralPath C:\sample\cupid$path.zip -DestinationPath C:\sample\cupid

tar -xvzf C:\sample\cupid\cupidmedia-mid-prod2-1_config.tar.gz -C C:\sample\cupid

while executing the batch file, the variable is not getting replaced in the powershell.

Daniel Schroeder

@Anandhan You would be much better off to ask these types of questions on Stack Overflow. At first glance my guess is the problem is that you don’t have a param section in your PowerShell.ps1 file. You should replace $path=$content with param($path).


Thank you very much. I was struggling to integrate powershell with Admin using Uipath and found this very useful. I have now created a post on this https://forum.uipath.com/t/uipath-invoke-powershell-as-administrator-using-batch-file/221063?u=huston8


Hi Daniel Schroeder Thanks for this good post and solution.

I have a question in this regard. How to output the PowerShell script outputs to a file or back to cmd console. You have any idea how to redirect the output.

I tried something similar but I ended up empty file PowerShell -NoProfile -ExecutionPolicy Bypass -Command “& ‘%PowerShellScriptPath%’ -Param1Name ‘Param 1 Value’ -Param2Name ‘Param 2 Value’ >psoutput.txt”


Hey.. I’m searching a lot but not getting solution. I’m running below command which is working fine in powershell but want to run in cmd for my batch file wherein getting error Start-Process : A parameter cannot be found that matches parameter name ‘path’.. Please please help.

powershell command start-Process Remove-Item -path “C:\Users$env:USERNAME\AppData\Local\Microsoft\Windows\Temporary Internet Files*” -Recurse -Force -EA SilentlyContinue -Verbose

How can i run this in through cmd for my batch file.


What if I wanted the Powershell script not only to be run with administrative privileges but at the same time with different credentials? A local user needs to execute the ps1 not only as admin, but as domain admin.


I’m here 8 years after the creation of this blog and thank you this helped me in my powershell script.


Thanks ! It was really helpful. But although my script is in accordance with your recommendations :

@ECHO OFF SET ScriptsDirectory=%~dp0 SET PowerShellScriptPath=%ScriptsDirectory%startup.ps1 PowerShell -NoProfile -ExecutionPolicy Bypass -Command “& {Start-Process PowerShell -ArgumentList ‘-NoProfile -ExecutionPolicy Bypass -File “””“%PowerShellScriptPath%””””’ -Verb RunAs}”;

it doesn’t work. When this “bat file” is launched it appears “User Account Control - Do you want to allow this app to make changes …” and asks to enter the administrator password. What I don’t want…
