Run multiple powershell commands from CSV

Question

Hi all. need some help running multiple powershell scripts. They are completed commands that I could just copy and paste into powershell and run....one at a time. but there is over 100 and it will take ages but I may just have to do that as it might be quicker then trying to find a solution

Is there an easier way just to put them in a CSV or text file and just hit one powershell command to run them all one after the other.

Answer 1

Just save the commands in a file with a .ps1 extension and then execute it.

Powershell.exe "C:\Temp\MyCmds.ps1."

Answer 2

Hello NikeshKanani-6547,

Thanks for reaching out.

To run multiple scripts sequentially you can use the -Wait parameter on Start-Process like so

$scriptsList =
@(
'C:\Users\WP\Desktop\Scripts\1.ps1'
'C:\Users\WP\Desktop\Scripts\2.ps1'
'C:\Users\WP\Desktop\Scripts\3.ps1'
)

foreach($script in $scriptsList)
{
Start-Process -FilePath "$PSHOME\powershell.exe" -ArgumentList "-command '& $script'" -Wait
}
PowerShell will wait for the current script to finish before running the next one.

Before you do this, know that this is a VERY, VERY, VERY BAD IDEA!

Import-CSV C:\Junk\BadIdea.csv |
    ForEach-Object{
        Invoke-Expression $_.RunThis
    }

Here's a CSV example:

RunThis
Get-Content c:\junk\badidea.csv
Get-Date
"123" -replace "2"

Now imagine some smart-a$$ put "Format-Volume -DriveLetter C" in there!!!
