timeout(1)

NAME
timeout - Start COMMAND, and kill it if still running after DURATION.

SYNOPSIS
timeout [-f|--foreground] [-k|--kill-after] [-p|--preserve-status] [-s|--signal] [-v|--verbose] [-h|--help] [-V|--version] <duration> <command>

DESCRIPTION
Start COMMAND, and kill it if still running after DURATION.

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
    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

<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

EXTRA
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. Exit status:
  124 if COMMAND times out, and --preserve-status is not specified
  125 if the timeout command itself fails
  126 if COMMAND is found but cannot be invoked
  127 if COMMAND cannot be found
  137 if COMMAND (or timeout itself) is sent the KILL (9) signal (128+9)
  - the exit status of COMMAND otherwise
