NAME

6       systemd-inhibit - Execute a program with an inhibition lock taken
7

SYNOPSIS

9       systemd-inhibit [OPTIONS...] [COMMAND] [ARGUMENTS...]
10
11       systemd-inhibit [OPTIONS...] --list
12

DESCRIPTION

14       systemd-inhibit may be used to execute a program with a shutdown,
15       sleep, or idle inhibitor lock taken. The lock will be acquired before
16       the 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].

OPTIONS

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       --no-pager
60           Do not pipe output into a pager.
61
62       --no-legend
63           Do not print the legend, i.e. column headers and the footer with
64           hints.
65
66       -h, --help
67           Print a short help text and exit.
68
69       --version
70           Print a short version string and exit.
71

EXIT STATUS

73       Returns the exit status of the executed program.
74

EXAMPLE

76           # systemd-inhibit wodim foobar.iso
77
78       This burns the ISO image foobar.iso on a CD using wodim(1), and
79       inhibits system sleeping, shutdown and idle while doing so.
80

ENVIRONMENT

82       $SYSTEMD_PAGER
83           Pager to use when --no-pager is not given; overrides $PAGER. If
84           neither $SYSTEMD_PAGER nor $PAGER are set, a set of well-known
85           pager implementations are tried in turn, including less(1) and
86           more(1), until one is found. If no pager implementation is
87           discovered no pager is invoked. Setting this environment variable
88           to an empty string or the value "cat" is equivalent to passing
89           --no-pager.
90
91       $SYSTEMD_LESS
92           Override the options passed to less (by default "FRSXMK").
93
94           Users might want to change two options in particular:
95
96           K
97               This option instructs the pager to exit immediately when Ctrl+C
98               is pressed. To allow less to handle Ctrl+C itself to switch
99               back to the pager command prompt, unset this option.
100
101               If the value of $SYSTEMD_LESS does not include "K", and the
102               pager that is invoked is less, Ctrl+C will be ignored by the
103               executable, and needs to be handled by the pager.
104
105           X
106               This option instructs the pager to not send termcap
107               initialization and deinitialization strings to the terminal. It
108               is set by default to allow command output to remain visible in
109               the terminal even after the pager exits. Nevertheless, this
110               prevents some pager functionality from working, in particular
111               paged output cannot be scrolled with the mouse.
112
113           See less(1) for more discussion.
114
115       $SYSTEMD_LESSCHARSET
116           Override the charset passed to less (by default "utf-8", if the
117           invoking terminal is determined to be UTF-8 compatible).
118
119       $SYSTEMD_COLORS
120           The value must be a boolean. Controls whether colorized output
121           should be generated. This can be specified to override the decision
122           that systemd makes based on $TERM and what the console is connected
123           to.
124
125       $SYSTEMD_URLIFY
126           The value must be a boolean. Controls whether clickable links
127           should be generated in the output for terminal emulators supporting
128           this. This can be specified to override the decision that systemd
129           makes based on $TERM and other conditions.
