Linux – How to Perform Binary Diff on Identical Files

Edit: Apparently there is a built in alias so this works too:

diff $(Get-Content C:\file1.txt) $(Get-Content C:\file2.txt)

You can do this:

Compare-Object $(Get-Content c:\file1.txt) $(Get-Content c:\file2.txt)

This is some sample output:

InputObject                             SideIndicator
-----------                             -------------
This is a line in file 2                =>
This is a line in file 1                <=

You can also do -excludeDifferent to only show the lines that are the same or -includeEqual to include the lines that are the same.

You should probably take a look at the rsync-related tools: rdiff and rdiff-backup. The rdiff command lets you produce a patch file and apply it to some other file.

The rdiff-backup command uses this approach to deal with entire directories, but I'm guessing you're working with single-file disk images, so rdiff will be the one to use.
