Can I get the backup option of cp and mv to work with directories?
2
--backup[=CONTROL]
make a backup of each existing destination file
The man page does say that it works on file. It doesn't seem to have any effect on directories. Is there anyway to make this work with directories as well? I want the destination directory, if it exists, to be backed up in the same way that a file would be backed up.

What does "work" mean for a directory? Are you trying to back up the information about the directory itself, or are you trying to organize the backed-up files into a separate back-up directory (instead of having each file backed up in the directory in which it is found)? Either way, "cp" will not do this for you; you need to write a script.

@IDAllen Yeah I have come to that same conclusion. Let me make the script an answer instead.

I have a feeling that there isn't, so I wrote this script which emulates the functionality:
#!/bin/bash
if [ -e "$target" ]
then
backup="$target.bak"
if [[ -e "$backup" ]]
then
count=0
while [[ -e "$backup.$count" ]]; do let "count += 1"; done
backup="$backup.$count"
fi
mv "$target" "$backup"
echo "backup file $backup created."
fi

I think you've written an archive and delete script, not a back-up script, since your script deletes the original directory (by renaming it). Your script comment about "file created" will mislead if it isn't a file. Depending on how you call your script (i.e. if you use it withfind), you may find that it archives all the files under a directory before it archives the directory itself, orfindwill complain that you've just moved away a directory that it was about to walk - this may not be what you want.
