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 m[blue]Inhibitor Lock Developer Documentationm[]

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.

SEE ALSO

systemd(1), logind.conf(5)
