timeout - timeout
NAME SYNOPSIS DESCRIPTION Arguments: OPTIONS Exit status:NAME
timeout − timeout
SYNOPSIS
timeout [OPTION] DURATION COMMAND...
DESCRIPTION
Start COMMAND, and kill it if still running after DURATION.
Arguments:
<duration>
a floating point number with an optional suffix: ’s’ for seconds (the default), ’m’ for minutes, ’h’ for hours or ’d’ for days ; a duration of 0 disables the associated timeout
<command>...
a command to execute with optional arguments
OPTIONS
−f, −−foreground
when not running timeout directly from a shell prompt, allow COMMAND to read from the TTY and get TTY signals; in this mode, children of COMMAND will not be timed out
−k, −−kill−after <kill−after>
also send a KILL signal if COMMAND is still running this long after the initial signal was sent
−p, −−preserve−status
exit with the same status as COMMAND, even when the command times out
−s, −−signal <SIGNAL>
specify the signal to be sent on timeout; SIGNAL may be a name like ’HUP’ or a number; see ’kill −l’ for a list of signals
−v, −−verbose
diagnose to stderr any signal sent upon timeout
−h, −−help
Print help
−V, −−version
Print version
Upon timeout, send the TERM signal to COMMAND, if no other SIGNAL specified. The TERM signal kills any process that does not block or catch that signal. It may be necessary to use the KILL signal, since this signal can’t be caught.
