Alternatively, use a "set -x" command inside the shell script... I
/believe/ most shells will honour a set -x command. That way you run in
the intended shell with tracing turned on.

As I was testing to see which shells supported the set -x command, I
find that on this Lucid installation, /etc/shells lists the following
shells as being available:

# /etc/shells: valid login shells
/bin/csh
/usr/bin/es
/usr/bin/ksh
/bin/ksh
/usr/bin/rc
/usr/bin/tcsh
/bin/tcsh
/usr/bin/esh
/bin/sh
/usr/bin/screen
/bin/dash
/bin/bash
/bin/rbash
/bin/false

However, I can't find any trace of ksh installed on this (default)
system. Can anyone confirm that the same is true in Karmic for me please
and I'll raise a bug if there's not already one there.
