TIMEOUT(1)                       User Commands                      TIMEOUT(1)

NAME
       timeout - run a command with a time limit
SYNOPSIS
       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
       --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 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.
