How to execute PowerShell commands from a batch file?

I have a PowerShell script to add a website to a Trusted Sites in Internet Explorer:

set-location "HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings"
set-location ZoneMap\Domains
new-item TESTSERVERNAME
set-location TESTSERVERNAME
new-itemproperty . -Name http -Value 2 -Type DWORD

I want to execute these PowerShell commands from a batch file. It seems simple when I have to run a single command, BUT in this case I have a sequence of related commands. I want to avoid creating a separate file for the PS script to be called from the batch - everything must be in the batch file.

The question is: How to execute PowerShell commands (or statements) from a batch file?

This is what the code would look like in a batch file(tested, works):

powershell -Command "& {set-location 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings'; set-location ZoneMap\Domains; new-item SERVERNAME; set-location SERVERNAME; new-itemproperty . -Name http -Value 2 -Type DWORD;}"

Based on the information from:

http://dmitrysotnikov.wordpress.com/2008/06/27/powershell-script-in-a-bat-file/

Type in cmd.exe Powershell -Help and see the examples.

This solution is similar to walid2mi (thank you for inspiration), but allows the standard console input by the Read-Host cmdlet.

pros:

• can be run like standard .cmd file
• only one file for batch and powershell script
• powershell script may be multi-line (easy to read script)
• allows the standard console input (use the Read-Host cmdlet by standard way)

cons:

• requires powershell version 2.0+

Commented and runable example of batch-ps-script.cmd:

<# : Begin batch (batch script is in commentary of powershell v2.0+)
@echo off
: Use local variables
setlocal
: Change current directory to script location - useful for including .ps1 files
cd %~dp0
: Invoke this file as powershell expression
powershell -executionpolicy remotesigned -Command "Invoke-Expression $([System.IO.File]::ReadAllText('%~f0'))"
: Restore environment variables present before setlocal and restore current directory
endlocal
: End batch - go to end of file
goto:eof
#>
# here start your powershell script

# example: include another .ps1 scripts (commented, for quick copy-paste and test run)
#. ".\anotherScript.ps1"

# example: standard input from console
$variableInput = Read-Host "Continue? [Y/N]"
if ($variableInput -ne "Y") {
    Write-Host "Exit script..."
    break
}

# example: call standard powershell command
Get-Item .

Snippet for .cmd file:

<# : batch script
@echo off
setlocal
cd %~dp0
powershell -executionpolicy remotesigned -Command "Invoke-Expression $([System.IO.File]::ReadAllText('%~f0'))"
endlocal
goto:eof
#>
# here write your powershell commands...

untested.cmd

;@echo off
;Findstr -rbv ; %0 | powershell -c - 
;goto:sCode
 
set-location "HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings"
set-location ZoneMap\Domains
new-item TESTSERVERNAME
set-location TESTSERVERNAME
new-itemproperty . -Name http -Value 2 -Type DWORD
 
;:sCode 
;echo done
;pause & goto :eof

Looking for the possibility to put a powershell script into a batch file, I found this thread. The idea of walid2mi did not worked 100% for my script. But via a temporary file, containing the script it worked out. Here is the skeleton of the batch file:

;@echo off
;setlocal ENABLEEXTENSIONS
;rem make from X.bat a X.ps1 by removing all lines starting with ';' 
;Findstr -rbv "^[;]" %0 > %~dpn0.ps1 
;powershell -ExecutionPolicy Unrestricted -File %~dpn0.ps1 %*
;del %~dpn0.ps1
;endlocal
;goto :EOF
;rem Here start your power shell script.

)

When calling multiline PowerShell statements from a batch file, end each line with a caret, except the last line. You don't have to have the extra spacing at the beginning of the line, that's my convention.

PowerShell set-location "HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings" ^
           set-location ZoneMap\Domains ^
           new-item TESTSERVERNAME ^
           set-location TESTSERVERNAME ^
           new-itemproperty . -Name http -Value 2 -Type DWORD

If you are piping into a cmdlet like Select-Object, you need to terminate with a semicolon to end the command, otherwise it will include the next line.

Powershell $disk = Get-WmiObject Win32_LogicalDisk -Filter """"DeviceID='D:'"""" ^| Select-Object Freespace; ^
           Exit ([math]::truncate($disk.freespace / 1GB))
