10
11 systemd-inhibit [OPTIONS...] --list
12
14 systemd-inhibit may be used to execute a program with a shutdown, sleep
15 or idle inhibitor lock taken. The lock will be acquired before the
16 specified command line is executed and released afterwards.
17
18 Inhibitor locks may be used to block or delay system sleep and shutdown
19 requests from the user, as well as automatic idle handling of the OS.
20 This is useful to avoid system suspends while an optical disc is being
21 recorded, or similar operations that should not be interrupted.
22
23 For more information see the Inhibitor Lock Developer Documentation[1].
24
26 The following options are understood:
27
28 --what=
29 Takes a colon-separated list of one or more operations to inhibit:
30 "shutdown", "sleep", "idle", "handle-power-key",
31 "handle-suspend-key", "handle-hibernate-key", "handle-lid-switch",
32 for inhibiting reboot/power-off/halt/kexec, suspending/hibernating,
33 the automatic idle detection, or the low-level handling of the
34 power/sleep key and the lid switch, respectively. If omitted,
35 defaults to "idle:sleep:shutdown".
36
37 --who=
38 Takes a short, human-readable descriptive string for the program
39 taking the lock. If not passed, defaults to the command line
40 string.
41
42 --why=
43 Takes a short, human-readable descriptive string for the reason for
44 taking the lock. Defaults to "Unknown reason".
45
46 --mode=
47 Takes either "block" or "delay" and describes how the lock is
48 applied. If "block" is used (the default), the lock prohibits any
49 of the requested operations without time limit, and only privileged
50 users may override it. If "delay" is used, the lock can only delay
51 the requested operations for a limited time. If the time elapses,
52 the lock is ignored and the operation executed. The time limit may
53 be specified in logind.conf(5). Note that "delay" is only available
54 for "sleep" and "shutdown".
55
56 --list
57 Lists all active inhibition locks instead of acquiring one.
58
59 -h, --help
60 Print a short help text and exit.
61
62 --version
63 Print a short version string and exit.
64
66 Returns the exit status of the executed program.
67
69 # systemd-inhibit wodim foobar.iso
70
71 This burns the ISO image foobar.iso on a CD using wodim(1), and
72 inhibits system sleeping, shutdown and idle while doing so.
