I'm learning about and writing my first PowerShell program, where I compare folders and files on two drives to find differences based on name and date. I'm checking a library of folders and files for differences between shipping and beta versions of software to help focus testing.
If I find an "unpaired" folder, then I don't want to list both the folder and its files in my output of differences. In this case, it is enough to know that there is a difference at the folder level. I'm checking a library of folders and files between shipping and beta versions of software to help focus testing. In the folders, there are only files, not subfolders.
I don't know how to filter the duplicate information. In the final version of my PowerShell program, I'll write the results (full pathnames) to a file. Will I have more powerful filtering capabilities if I store the Get-ChildItem and Compare-Object results in files or arrays rather than variables?
This is a simplified program that I'm writing to test ideas for the final program:
I've included my console output and pointed out the extraneous information in a comment block following the test program.
