Find files which does not contains selected string

Question

I am trying to find all files, which does not contains a selected string. Find files which contains is easy:

gci | select-string \"something\"

Answer 1

As mentionend in How do I output lines that do not match 'this_string' using Get-Content and Select-String in PowerShell?

Select-String has the NotMatch parameter.

So you could use it:

gci | Select-String -notmatch "something"
