linux - signals used by the timeout command -


i want run program timeout. i'm doing using timeout command this

timeout 5 path/to/program

program using time-related signals: blocking, unblocking , raising sigalrm , sigvtalrm. don't know how timeout works, guess uses time signals. should worried signals program interfere timeout , vice versa?

by default, timeout send sigterm (unless change -s). therefore, shouldn't see conflict other signals.

fyi, if program exited timeout, have return value of 124. can force kill (if doesn't die gracefully) using -k seconds give return value of 137.
