@Charles Duffy on another thread answered this. not exit a bash script when one of the sub-script fails
set +e undoes set -e. However, using set -e is a bad idea in general; better to use || exit on individual commands where you want a nonzero exit status to be fatal. (Skip past the parable to the exercises if you're in a hurry). – Charles Duffy
