Add a "duplicate" command

[mgiugliano]

It would be cool if a "duplicate" command could be added.. Edit: Copy/Paste seem to work only across folders, not within the same folder.

Perhaps something like (note: I am not a bash god)

cp "${f[l]}" "copy_${f[l]}" ;;

Similiar suggestion: A backup command that will execute something along cp "${f}" "${f}-$(date +'%Y%m%d_%H%M%S').bak".
