I would like to get only the de_mirage as a variable. So if a map changes, then it will be de_dust2 or de_inferno and so on. Does anybody know a solution for this?

Thank you!

When using Get-Content, each line is passed down the pipeline one at a time, unless specifying the -Raw switch. The reason I bring this up is due to your Select cmdlet that you're piping to. When you specified the parameter of -First, with a value of 1, you're only grabbing the first line, and then trying to find the pattern in the first line.

Here's my poor attempt at RegEx:

Get-Content -Path $demo | Where-Object -FilterScript { $_ -match 'de_\w ' }
$Matches[0]

. . .where the $Matches Automatic Variable contains all the matched RegEx patterns (as the name indicates) stored in an array format; where we use the index number to reference the value. This would also work piping to Select-String when searching for a Pattern just like you had done.
