If you're after a graphical diff command, you should give Meld a go. It's a visual diff and merge tool. I think it is present by default on Ubuntu systems

One downside of Meld - seems like it can only diff existing files, you can't simply copy/paste content into two editor windows to diff them spontaneously –  matt b Mar 29 '11 at 17:59
Yes you can - File→New..., leave file paths empty and press OK, then you can paste. –  Beni Cherniavsky-Paskin Jun 28 '12 at 9:03

Diffuse works well.

I use KDiff3. It is one of the best tools available for comparison or merging two or three text input files or directories.

If your looking for command line diff would work wouldn't it? For graphical and not free I like Beyond Compare

Just tried Meld. It wasn't installed by default but it is available from the repo. sudo apt-get install meld –  Gren Aug 13 '09 at 18:39

Besides the obvious 'git diff' gnu emacs has a mode for diff (obviously :-), called ediff. And there is a relatively standard graphical interface for git, called gitk. Below is a screenshot of ediff.
