• In order to directly run PowerShell® script code from a JS7 shell job script the recommended approach is to use a shebang replacement like this:

  Code Block
  language bash title Example how run PowerShell® script code with a shebang replacement linenumbers true
  @@setlocal enabledelayedexpansion & set f=%RANDOM%.ps1 & @@findstr/v "^@@[fs].*&" "%~f0" | > !f! & powershell.exe -NonInteractive -Command -File !f! & set e=!errorlevel! & del /q !f! & exit !errorlevele!/b& Write-Output "Hello" Write-Output "world"

  Explanation:

  • If you consider this shebang replacement somewhat cryptic then add it to JS7 - Script Includes which are easily referenced from shell jobs, e.g. by using ##!include pwsh
  • The PowerShell® pwsh.exe executable is available starting with PowerShell 6.0. PowerShell releases 5.x use the executable powershell.exe that can be used with the shebang accordingly. 

    Therefore if when using a version > 5.1 please change powershell.exe to pwsh.exe:

    @@setlocal enabledelayedexpansion & set f=%RANDOM%.ps1 & @@findstr/v "^@@[fs].*&" "%~f0"

    |

     > !f! & pwsh.exe -NonInteractive

    -Command - & exit !errorlevel

     -File !f! & set e=!errorlevel! & del /q !f! & exit !e!/b&

• As a bad alternative the PowerShell® executable can be invoked directly and can be parameterized like this:

  Code Block
  language bash title Example how to run PowerShell® script code from a single line linenumbers true
  pwsh.exe -NoLogo -NonInteractive -Command "& { Echo ""Flight Destination: $env:FLIGHT_DESTINATION""; Echo ""Booking Code: $env:BOOKING_CODE""; }"

  Explanation:

  • Consider the quoting: when using the -Command parameter then the PowerShell® script has to be specified from a string. This includes:
    
    • quoting the script by double quotes.
    • quoting code inside the script with two double quotes or using single quotes.
  • Note that each PowerShell® command has to be terminated with a semicolon.
