  There are also bash options which will do things like echo commands
before executing them.  The one I remember off the top of my head is
"bash -x script", which gives you debugging tracing on everything.  I
seem to recall there are ways to tweak that output to make it more
useful and less "gobs of debugging information".

  So, yeah, bash can save a lot of work when it comes to
debugging/tracing scripts.
