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.
The following options are understood:
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".
Takes a short, human-readable descriptive string for the program taking the lock. If not passed, defaults to the command line string.
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.
Do not pipe output into a pager.
Do not print the legend, i.e. column headers and the footer with hints.
- -h, --help
Print a short help text and exit.
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.
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.
Override the options passed to less (by default "FRSXMK").
Users might want to change two options in particular:
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.
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.
Override the charset passed to less (by default "utf-8", if the invoking terminal is determined to be UTF-8 compatible).
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.
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.
