timeout is part of
coreutils, so it’s probably already installed on your computer.
This command is pretty simple: type
timeout, a time limit and the target command:
timeout <DURATION> <COMMAND>
<DURATION>: a floating point number with an optional suffix:
s(seconds, the default),
As an example, to limit the duration of a python script to 2 minutes:
timeout 2m python3 myscript.py
After 2 minutes, the target command (
python3 myscript.py) will be killed (
TERM signal). To change the kill signal, use
<SIGNAL> can be a name or a number. Run
kill -l for a list of signals.
