On the command line, bash reacts like:
abacus(42):~$ exec nonesuch || echo here
exec: nonesuch: not found
here
But that's only in interactive shells. I have seen more elaborate
.forward files (I'm making this up right now):
"| IFS=' ' && p=/usr/local/bin/procmail && if [ -x $p ]; then $p -Yf-;
else exit 75; fi # revjack"
(This should be one line.)
