In a way that's what it does because only one exit status really counts for
anything: code 0. If it exits with code zero, do like Marin suggested:
touch $@
If it doesn't exit cleanly, the file won't be updated, so it will be out of
date on the next run. i did something similar to implement steps of a
long-running db anonymization process some years ago - it could run for
days at a time and be interrupted by, as you say, menial things. In my
case, each step of the process had a tag file associated with it ("step1",
"step17", etc.). On successful completion of the step, its file would be
created. That also allowed us, aside from error recovery, to easily
abort/continue the process at logic transition points in the process, as
well as "fake" steps by creating their marker files manually.
