SYSTEMD-INHIBIT(1) systemd-inhibit SYSTEMD-INHIBIT(1)
systemd-inhibit - Execute a program with an inhibition lock taken
systemd-inhibit [OPTIONS...] [COMMAND] [ARGUMENTS...]
systemd-inhibit [OPTIONS...] --list
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].
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.
--no-pager
Do not pipe output into a pager.
--no-legend
Do not print the legend, i.e. column headers and the footer with
hints.
-h, --help
Print a short help text and exit.
--version
Print a short version string and exit.
Returns the exit status of the executed program.
# 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.
$SYSTEMD_PAGER
Pager to use when --no-pager is not given; overrides $PAGER. If
neither $SYSTEMD_PAGER nor $PAGER are set, a set of well-known
pager implementations are tried in turn, including less(1) and
more(1), until one is found. If no pager implementation is
discovered no pager is invoked. Setting this environment variable
to an empty string or the value "cat" is equivalent to passing
--no-pager.
$SYSTEMD_LESS
Override the options passed to less (by default "FRSXMK").
Users might want to change two options in particular:
K
This option instructs the pager to exit immediately when
Ctrl+C is pressed. To allow less to handle Ctrl+C itself to
switch back to the pager command prompt, unset this option.
If the value of $SYSTEMD_LESS does not include "K", and the
pager that is invoked is less, Ctrl+C will be ignored by the
executable, and needs to be handled by the pager.
X
This option instructs the pager to not send termcap
initialization and deinitialization strings to the terminal.
It is set by default to allow command output to remain
visible in the terminal even after the pager exits.
Nevertheless, this prevents some pager functionality from
working, in particular paged output cannot be scrolled with
the mouse.
See less(1) for more discussion.
$SYSTEMD_LESSCHARSET
Override the charset passed to less (by default "utf-8", if the
invoking terminal is determined to be UTF-8 compatible).
$SYSTEMD_COLORS
The value must be a boolean. Controls whether colorized output
should be generated. This can be specified to override the
decision that systemd makes based on $TERM and what the console
is connected to.
$SYSTEMD_URLIFY
The value must be a boolean. Controls whether clickable links
should be generated in the output for terminal emulators
supporting this. This can be specified to override the decision
that systemd makes based on $TERM and other conditions.
