I am trying to use Powershell to compare two files and save the results into a file.
This is working ok. However I would like the output to include the line numbers.

I saw one forum suggest this could be done by comparing array, looking for some other feedback / examples.

$mydiff = Compare-Object $(Get-Content $myfile1) $(Get-Content $myfile2) | Out-String

Thank you,
Mark

something like:

compare-object $(get-content .\test1.txt) $(get-content .\test2.txt) | % {SELECT-string -path .\test1.txt -pattern $_.InputObject }

compare-object is not able to do that. And as long as your lines are not unique, you cannot combine the result of it with the files to get the line number. You will need to write your own compare cmdlet for that, comparing two string arrays line by line.
IMHO it is much easier to use any of the existing external tools, like diff.exe, to do the comparision.

I had Compare-IT , really great tool. It had command line support. With this I sent powershell to grab the file paths and let compare it create html files with the diff results.

Thanks.
