Get current working directory name in Bash Script

Question

How would I get just the current working directory name in a bash script, or even better, just a terminal command.

pwd gives the full path of the current working directory, e.g. '/opt/local/bin' but I only want 'bin'

Answer 1

Use the basename program. For your case::

% basename $PWD
bin

Answer 2

You can use a combination of pwd and basename. E.g.

#!/bin/bash

CURRENT=`pwd`
BASENAME=`basename $CURRENT`

echo $BASENAME

exit;

Answer 3

No need for basename, and especially no need for a subshell running pwd (which adds an extra, and expensive, fork operation); the shell can do this internally using parameter expansion:

${PWD##*/}

Answer 4

$ echo ${PWD##*/}
