To perform a syntax check/dry run of your bash script run:
bash -n myscript.sh

To produce a trace of every command executed run:
bash -v myscripts.sh

To produce a trace of the expanded command use:
bash -x myscript.sh

-v and -x can also be made permanent by adding
set -o verbose and set -o xtrace to the script prolog.
This might be useful if the script is run on a remote machine, e.g.
a build-bot and you are logging the output for remote inspection.
