Try a shell script.  I'm guessing it would involve "for file in $1" and tr, but I'm not sure.  I would like to hear how you do it because I'm interested in a similar thing.  Also converting spaces to underscores would be good too.  ;)

Can you believe that I had a similar question myself? I think that a shell script would propably do the job as Faust wrote, but I really suck at shell scripting.   :rolleyes:  

So, if anyone has an answer to this, could you please share it with us?   (http://smile.gif)

for the underscore i believe something like:
ls | while read item; do mv "$item" `echo "$item" | sed 's/\ /_/g'`; done

might want to double check on the sed part, s and g might need to be reversed. it's been a while but that should work. for subdirectories you could do find instead of ls

There is a problem with the script if the directory name is in Uppercase. Is there another alternative?

thanks

Yup, just had to only make the conversions effect the last directory element  (http://smile.gif)

hi!

The directory thing works now....but not the uppercase to lower case. Am attaching the output below....

mv: `/mnt/Setups/linux/window_managers/gkrellm/Acqua.gkrellm.tar.gz' and `/mnt/Setups/linux/window_managers/gkrellm/Acqua.gkrellm.tar.gz' are the same file

mv: `/mnt/Setups/linux/window_managers/gkrellm/CoplandOS.gkrellm.tar.gz' and `/mnt/Setups/linux/window_managers/gkrellm/CoplandOS.gkrellm.tar.gz' are the same file

mv: `/mnt/Setups/linux/window_managers/gkrellm/theme_MonkeyLovers.tar.gz' and `/mnt/Setups/linux/window_managers/gkrellm/theme_MonkeyLovers.tar.gz' are the same file

hmm try putting this line in front of the `mv' command in the script and post the output here.

echo "$file::$newf"

see, that shouldn't be able to happen because it checks if the files are still the same before it does 'mv'. i might of messed up somewhere (was in a hurry  (http://smile.gif) )
