NAME         top

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

SYNOPSIS         top

       systemd-inhibit [OPTIONS...] [COMMAND] [ARGUMENTS...]

       systemd-inhibit [OPTIONS...] --list

DESCRIPTION         top

       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

OPTIONS         top

       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

           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

       -h, --help
           Print a short help text and exit.

           Print a short version string and exit.

EXIT STATUS         top

       Returns the exit status of the executed program.

EXAMPLE         top

           # 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.

ENVIRONMENT         top

           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

           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.
