Quickly! Wade</blockquote><div> Yes, there is. If the files are all currently in the same directory, and are all named something_or_other.jpg, the following will rename them to 1.jpg, 2.jpg, in a random-ish order: $ for i in *.jpg ; do mv $i $((++c)).jpg ; done $ unset c $ unset i The "for i in FOO ; do BAR ; done" part runs a particular command once for each file specified by FOO. The precise command is specified by BAR, and it renames (mv) that file to a number followed by ".jpg"; it also adds one to the number so that each file gets a different number. "unset c" and "unset i" just clear the values of those two shell variables; if you close the terminal window afterwards, you won't need to run those two commands. Holler if you need more help, or if I misunderstood your problem. </div></div> </blockquote></div> One other thing: if your files aren't completely randomly-named and there's a piece of the filename that you need to keep, (i.e., you want to rename DSCF00012.jpg to 12.jpg) check out mmv (it's in universe).
