In bourne-compatible shells (/bin/sh, bash) run 'set -x' or pass the -x
flag during invocation to turn on debug output. The shell will print out
each command it is about to invoke.

The output requires some interpretation, as it can get confusing in the
presence of variable expansion, pipelines, and subshells; but it should
be adequate for a simple list of commands.
