        Yes, and that's why I wrote it.  Eric's solution is indeed fine for the 
case of no spaces or other odd characters; mine will work for that and 
files named "Bob's Cat & my Dog #3.jpg".  ;)

        Mmmmm... Perl!  For another way to get to the same place, you can also 
use the ${name//pattern/replace} in Bash.  Thus:

for f in *.jpg ; do echo mv "${f}" "BobsCat${f//\ /_}" ; done

        (Replace all spaces in any filename with _, and prepend "BobsCat" to 
all 
names.  Remove "echo" above for full functionality.  ;)  Somewhere I have 
a script I wrote that removes spaces, HTML-encoded spaces ("%20"), 
*double* spaces, and some other junk; if someone wants that I can find it 
and send or post it.

        BTW, entirely in the other direction, for those who'd like to rename 
tons 
of files graphically, there's a utility called "krename" 
(www.krename.net) that can do it even using embedded mp3/vorbis tags.  At 
last, a way to get all of my music files into my naming-convention of the 
month!  I'll be going to check it out after posting this.

Now that's enough off-topic-ness from me...
