So the utility Diff works just like I want for 2 files, but I have a project that requires comparisons with more than 2 files at a time, maybe up to 10 at a time. This requires having all those files side by side to each other as well. My research has not really turned up anything, vimdiff seems to be the best so far with the ability to compare 4 at a time.
My question: Is there any utility to compare more than 2 files at a time, or a way to hack diff/vimdiff so it can do multiple comparisons? The files I will be comparing are relatively short so it should not be too slow.
Displaying 10 files side-by-side and highlighting differences can be easily done with Diffuse. Simply specify all files on the command line like this:
diffuse 1.txt 2.txt 3.txt 4.txt 5.txt 6.txt 7.txt 8.txt 9.txt 10.txt
