I need you to help me study to propose a script that compares 2 text files and creates one for me with the same strings. How would you do it? I just need advice.

file1.txt
C:\tmp\1\11111.mp3
C:\tmp\1\11112.mp3
C:\tmp\3\11113.mp3

file2.txt
C:\tmp\1\11111.mp3
C:\tmp\2\11112.mp3
C:\tmp\3\11113.mp3

result.txt
C:\tmp\1\11111.mp3
C:\tmp\3\11113.mp3

    Use Compare-Object: 

    (Compare-Object -ReferenceObject (Get-Content c:\junk\file1.txt) -DifferenceObject (Get-Content c:\junk\file2.txt) -IncludeEqual -ExcludeDifferent).InputObject |
    Out-File c:\junk\resultfile.txt
