timeout


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.

       --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, 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.  For other processes, it may  be  necessary
       to use the KILL (9) signal, since this signal cannot be caught.
