systemd-inhibit

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.
