How to change the value of a line in a cmd script?

Question

I have this cmd script:

REM Environment-Variables which can be used for Programs
REM ----------------------------------------------------------------
set SDENVDataPool=13
set SDENVDataPoolPath=C:\ProgramData\

The value 13 must be changed. I have tried this solution:

$line = Get-Content .\script.cmd | Select-String -Pattern "set SDENVDataPool" | Select-Object -ExpandProperty Line
$content = Get-Content .\script.cmd
$content | ForEach-Object {$_ -replace $line, "set SDENVDataPool=14"} | Set-Content .\script.cmd

The problem is that the line isn't read correctly. I get the whole file.

Can anyone help me?

In your Select-String -Pattern "set SDENVDataPool" you are returning more than one line as both set SDENVDataPool=13 & set SDENVDataPoolPath=C:\ProgramData\ match that pattern. If you change your Pattern to Select-String -Pattern "set SDENVDataPool=" you should correctly return one match which you can then use in the rest of your script to set the content when you run this portion

$content | ForEach-Object {$_ -replace $line, "set SDENVDataPool=14"} | Set-Content .\script.cmd
