Question

I’m trying to count all text files in a folder that contains all strings in a set of strings, i.e. basically an AND-operator. The order of the string in each file may way and preferably I’m looking for a one-liner.

I.e. I’m trying to accomplish something like:

(Get-ChildItem -filter "file*" C:\temp |
Select-String -Pattern @(“str1", "str2")).Count

but with the difference that the above statement counts all files containing either “str1” or “str2” but I’m trying to do an AND-operation instead of an OR, thus count only files that contains both “str1” and “str2”.

This perhaps can do the job with a -AND operator :

(Get-ChildItem . -include *.txt -recurse |
    % {(Select-String $_ -Pattern "str1") -AND (select-string $_ -pattern "str2")} |
        where {$_ -eq $true}).count
