Hello Just looking at this man page. I appreciate not the latest version. GNU coreutils 8.32
https://man7.org/linux/man-pages/man1/timeout.1.html Could it be clarified that a timeout DURATION of 0 also specifically inhibits the -k, --kill-after=DURATION ? it's implied as "this long after the initial signal was sent", so I'm suggesting to make it clearer. ie $ time timeout -k 2 0 sleep 3 real 0m3.005s user 0m0.004s sys 0m0.000s Maybe it could be updated: -k, --kill-after=DURATION also send a KILL signal if COMMAND is still running this long after the initial signal was sent. This never occurs if the initial signal was inhibited by a duration of 0 Cheers, Jonny
