[hacknews] procalive

henry@utzoo.UUCP (Henry Spencer) (11/02/84)

Kill(1) has had a -e option added to permit use of the new signal 0 to
test for the existence of processes.  Procalive(1) is a new utility
which uses kill -e in the appropriate way, returning an exit code suitable
for use in shell programs.
