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"

Answer 2

I'm not sure if it can be done without the foreach-object but this works:

gci |foreach-object{if (-not (select-string -inputobject $_ -Pattern "something")){$_}}

Answer 3

You can use Where-Object;

gci | Where-Object { !( $_ | Select-String "something" -quiet) }
