Hello!
I am not familiar with UNIX and I have this problem:

I need to move files from a UNIX machine to a PC. UNIX file names contain ":" as special character which is not recognized in a PC.
How can I change ":" for "_" in the name of a bunch of files in UNIX?

Thanks for your help.

Thank you for your help!

Hi!
I tried the procedure described and I could change the file names inside the main folder. I would like this process to include any subfolders and files included in the main folder (and not repeating it in each folder!).
Thanks!

extending previous solution for subfolders:

for file in `find .`
do
mv $file `echo $file | sed 's/:/_/g'`
done

I'd suggest adding a '-type f' to the find command to to avoid it matching directories too?

i would suggest using while loop instead. ( although it should be ok with a for loop if files with spaces are properly parsed)
