sh(1) can do this alone, without recourse to any external programs.

path='/usr/local/etc/filename'
fname=${path##*/}
echo $fname

There is also an external program basename(1)

The same trick with sed(1):

fname=$( echo $path | sed -e 's,^.*/,,' )

but the built-in prefix matching stuff is preferable since it is more
efficient.
