# Bash traceback
#
# Because the option “set -o errexit” / "set -e" does not show any message when
# it stops your Bash script in some cases (for example var=$(yourcommand) will
# exit without any message, even when yourcommand returns an exit code
# different from zero), I recommend you to add the code below to your bash scripts
# to show a traceback each time “errexit” forces your Bash script to stop.
