There were some other suggestions, which were not diff tools in their own right, which I will list below:
- It (Beyond Compare) runs well in Wine, but I miss the shell integration. - Danyal Aytekin, May 11 '12, 13:01
- Eclipse also has a fairly decent comparison mechanism. - JeeBee, Oct 9 '08, 12:45
- P4Merge that comes with Perforce is pretty good and comes for free with perforce client. Both terminal and GUI version. - amok, Jul 7 '10, 23:19
- I had to use Vim because most of diffs mentioned here do not understand UTF-8. - user184880, Oct 6 '09, 9:56
That about wraps up that thread's merge into this one, as covered here.
FileMerge is bundled with XCode, but I prefer Kaleidoscope which is not free.
I use Kaleidoscope. Or just plain, old diff from the CLI
It is not great, but the FileMerge bundled with the OS can be launched from the command line as opendiff a.txt b.txt.
