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
## Examples Run `sleep 10` and terminate it after 3 seconds: timeout 3s sleep 10 Send a signal to the command after the time limit expires (`TERM` by default, `kill -l` to list all signals): timeout {{[-s|--signal]}} {{INT|HUP|KILL|...}} {{5s}} {{sleep 10}} Send verbose output to `stderr` showing signal sent upon timeout: timeout {{[-v|--verbose]}} {{0.5s|1m|1h|1d|...}} {{command}} Preserve the exit status of the command regardless of timing out: timeout {{[-p|--preserve-status]}} {{1s|1m|1h|1d|...}} {{command}} Send a forceful `KILL` signal after certain duration if the command ignores initial signal upon timeout: timeout {{[-k|--kill-after]}} {{5m}} {{30s}} {{command}} > The examples are provided by the [tldr-pages project](https://tldr.sh) under the [CC BY 4.0 License](https://github.com/tldr-pages/tldr/blob/main/LICENSE.md). > > Please note that, as uutils is a work in progress, some examples might fail.
