timeout — run a command with a time limit
timeout
[OPTION
] DURATION
COMMAND
[ARG
...]
timeout
[OPTION
]
Start COMMAND, and kill it if still running after DURATION.
Mandatory arguments to long options are mandatory for short options too.
−−preserve−status
exit with the same status as COMMAND, even when the command times out
−−foreground
When not running timeout directly from a shell prompt, allow COMMAND to read from the TTY and receive TTY signals. In this mode, children of COMMAND will not be timed out.
−k
, −−kill−after
=DURATION
also send a KILL signal if COMMAND is still running this long after the initial signal was sent.
−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
−−help
display this help and exit
−−version
output version information and exit
DURATION is a floating point number with an optional suffix: 's' for seconds (the default), 'm' for minutes, 'h' for hours or 'd' for days.
If the command times out, and −−preserve−status
is not
set, then exit with status 124. Otherwise, exit with the
status of COMMAND. If no signal is specified, send the TERM
signal upon timeout. The TERM signal kills any process that
does not block or catch that signal. It may be necessary to
use the KILL (9) signal, since this signal cannot be caught,
in which case the exit status is 128+9 rather than 124.
