I want to add the ".sbd" after all files ending on ".utf8" in a directory I do not want to replace the extensions, but really want to add them so the filenames will look like "filename.utf8.sbd" I think I should adapt the following code, but don't manage to find out exactly how 

for f in *.utf8 ; do mv "$f" "$f.sbd" ; done

Can anyone help me? I am very new to the command line Thanks a bunch!

Your code should work if no file has spaces (or other "special" character) in the name and if the directory is not pathologically big.

In those cases, you can use something like this:

ls|grep '*.utf8$'|while read i; do mv "$i" "$i.sbd"; done
