I've been Googling around for a while looking for a "ls" script that would highlight versioned/non-versioned files differently (or even display a tag next to their filename Added/Modified/Deleted/etc.).
I haven't found anything, so if you're looking for a fun project, here's one :) I would build it myself but I'm still a noob at shell scripting.
I've talked to a couple of friends about this project and they all seemed to like the idea.
If anyone's interested in building this, keep us updated here !
UPDATE: I've found this script that colorizes some svn commands: http://snipplr.com/view.php?codeview&id=28748
