I'm on a Mac and the cp and mv commands are killing me due to them copying the contents of a directory if a trailing slash is present. It has bitten me more than once when I use tab completion to specify the directory I want to copy.

I have noticed zsh has a neat feature that removes the trailing slash if it's not needed after a space or enter key is pressed. Is there any way to have bash mimic this behavior?

Why not just run zsh? It's built into Mac OS X. – Spiff Nov 30 '11 at 7:51
I guess I'm just used to bash after 12 years of using it... zsh seems like it requires a lot of setup to get it working similar to bash? – intargc Nov 30 '11 at 16:04

Bash completion can't capture space or enter key. It's for tab-key only.

To your question, I think you can write a little wrapper script to remove the trailing slash before pass the command line to the actual cp/mv programs.

For example, ~/bin/my_mv:


last="${argv[$# - 1]}"
argv[$# - 1]="$last"

mv "${argv[@]}"
