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
For more information see the Inhibitor Lock DeveloperDocumentation.
The following options are understood:
Takes a colon-separated list of one or more operations to
inhibit: "shutdown", "sleep", "idle", "handle-power-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".
Takes a short, human-readable descriptive string for the program
taking the lock. If not passed, defaults to the command line
Takes a short, human-readable descriptive string for the reason
for taking the lock. Defaults to "Unknown reason".
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".
Lists all active inhibition locks instead of acquiring one.
Print a short help text and exit.
Print a short version string and exit.
