Greetings! Did you try this: b=`sed -e s/:/-/g $a` #Replace all colons in the string $a with dashes and then use the name $b.tar instead of $a.zip (I'd use the .tar instead of .zip for a tar archive. Helps with consitency)? I know I used that line in order to strip empty spaces from filenames, replacing them with underscores. Hope this helps! -Henrik W Lund
