NAME

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

SYNOPSIS

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

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

DESCRIPTION

       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].

OPTIONS

       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.

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

       --version
           Print a short version string and exit.

EXIT STATUS

       Returns the exit status of the executed program.

EXAMPLE

           # 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

       $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").

       $SYSTEMD_LESSCHARSET
           Override the charset passed to less (by default "utf-8", if the invoking terminal is
           determined to be UTF-8 compatible).
