As said by others, you can use `basename`. Apart from this, you can
fix your old habit by prepending a '/' before '$0', like this:

#! /bin/sh
PROGNAME=`echo /$0 |awk 'BEGIN{FS="/"}{print $NF}'`

Last, you can also use variable expansions mechanisms by saying:


The main difference with `basename` way is that the latter do not call
a subprogram.

(If you are sure there is no space in your name, you can remove the
quotes, but are you sure?)

See `Parameter Expansion' in sh(1).
