SYSTEMD-INHIBIT(1)              systemd-inhibit             SYSTEMD-INHIBIT(1)

NAME
       systemd-inhibit - Execute a program with an inhibition lock taken

SYNOPSIS
       systemd-inhibit [OPTIONS...] [COMMAND] [ARGUMENTS...]

       systemd-inhibit [OPTIONS...] --list

DESCRIPTION
       systemd-inhibit may be used to execute a program with a shutdown,
       sleep, or idle inhibitor lock taken. The lock will be acquired before
       the specified command line is executed and released afterwards.

       Inhibitor locks may be used to block or delay system sleep and shutdown
       requests from the user, as well as automatic idle handling of the OS.
       This is useful to avoid system suspends while an optical disc is being
       recorded, or similar operations that should not be interrupted.

       For more information see the Inhibitor Lock Developer Documentation[1].

OPTIONS
       The following options are understood:

       --what=
           Takes a colon-separated list of one or more operations to inhibit:
           "shutdown", "sleep", "idle", "handle-power-key",
           "handle-suspend-key", "handle-hibernate-key", "handle-lid-switch",
           for inhibiting reboot/power-off/halt/kexec, suspending/hibernating,
           the automatic idle detection, or the low-level handling of the
           power/sleep key and the lid switch, respectively. If omitted,
           defaults to "idle:sleep:shutdown".

       --who=
           Takes a short, human-readable descriptive string for the program
           taking the lock. If not passed, defaults to the command line
           string.

       --why=
           Takes a short, human-readable descriptive string for the reason for
           taking the lock. Defaults to "Unknown reason".

       --mode=
           Takes either "block" or "delay" and describes how the lock is
           applied. If "block" is used (the default), the lock prohibits any
           of the requested operations without time limit, and only privileged
           users may override it. If "delay" is used, the lock can only delay
           the requested operations for a limited time. If the time elapses,
           the lock is ignored and the operation executed. The time limit may
           be specified in logind.conf(5). Note that "delay" is only available
           for "sleep" and "shutdown".

       --list
           Lists all active inhibition locks instead of acquiring one.

       -h, --help
           Print a short help text and exit.

       --version
           Print a short version string and exit.

EXIT STATUS
       Returns the exit status of the executed program.

EXAMPLE
           # systemd-inhibit wodim foobar.iso

       This burns the ISO image foobar.iso on a CD using wodim(1), and
       inhibits system sleeping, shutdown and idle while doing so.
