NAME

6       timeout - run a command with a time limit
7

SYNOPSIS

9       timeout [OPTION] DURATION COMMAND [ARG]...
10       timeout [OPTION]
11

DESCRIPTION

13       Start COMMAND, and kill it if still running after DURATION.
14
15       Mandatory  arguments  to  long  options are mandatory for short options
16       too.
17
18       --preserve-status
19
20              exit with the same status as COMMAND, even when the
21
22              command times out
23
24       --foreground
25
26              when not running timeout directly from a shell prompt,
27
28              allow COMMAND to read from the TTY and get TTY signals; in  this
29              mode, children of COMMAND will not be timed out
30
31       -k, --kill-after=DURATION
32
33              also send a KILL signal if COMMAND is still running
34
35              this long after the initial signal was sent
36
37       -s, --signal=SIGNAL
38
39              specify the signal to be sent on timeout;
40
41              SIGNAL may be a name like 'HUP' or a number; see 'kill -l' for a
42              list of signals
43
44       -v, --verbose
45              diagnose to stderr any signal sent upon timeout
46
47       --help display this help and exit
48
49       --version
50              output version information and exit
51
52       DURATION is a floating point number with an optional  suffix:  's'  for
53       seconds  (the default), 'm' for minutes, 'h' for hours or 'd' for days.
54       A duration of 0 disables the associated timeout.
55
56       If the command times out, and --preserve-status is not set,  then  exit
57       with  status  124.   Otherwise, exit with the status of COMMAND.  If no
58       signal is specified, send the TERM signal upon timeout.  The TERM  sig‐
59       nal kills any process that does not block or catch that signal.  It may
60       be necessary to use the KILL (9) signal, since this  signal  cannot  be
61       caught, in which case the exit status is 128+9 rather than 124.

BUGS

64       Some platforms don't currently support timeouts beyond the year 2038.
