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.
