TIMEOUT(1)                       User CommandsTIMEOUT(1)NAME       timeout - run a command with a time limitSYNOPSIS       timeout [OPTION] DURATION COMMAND [ARG]...       timeout [OPTION]DESCRIPTION       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 get 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       -v, --verbose              diagnose to stderr any signal sent upon timeout       --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.       A duration of 0 disables the associated timeout.       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  sig-       nal 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.BUGS       Some platforms don't currently support timeouts beyond the year 2038.AUTHOR       Written by Padraig Brady.REPORTING BUGS       GNU coreutils online help: <https://www.gnu.org/software/coreutils/>       Report    timeout    translation   bugs   to   <https://translationpro-       ject.org/team/>COPYRIGHT       Copyright (C) 2018 Free Software Foundation, Inc.
