+.SH "DESCRIPTION"
+.PP
+\fBsystemd\-inhibit\fR
+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\&.
+.PP
+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\&.
+.PP
+For more information see the
+\m[blue]\fBInhibitor Lock Developer Documentation\fR\m[]\&\s-2\u[1]\d\s+2\&.
+.SH "OPTIONS"
+.PP
+The following options are understood:
+.PP
+\fB\-\-what=\fR
+.RS 4
+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/soft\-reboot, 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"\&.
+.RE
+.PP
+\fB\-\-who=\fR
+.RS 4
+Takes a short, human\-readable descriptive string for the program taking the lock\&. If not passed, defaults to the command line string\&.
+.RE
+.PP
+\fB\-\-why=\fR
+.RS 4
+Takes a short, human\-readable descriptive string for the reason for taking the lock\&. Defaults to "Unknown reason"\&.
+.RE
+.PP
+\fB\-\-mode=\fR
+.RS 4
+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
+\fBlogind.conf\fR(5)\&. Note that
+"delay"
+is only available for
+"sleep"
+and
+"shutdown"\&.
+.RE
+.PP
+\fB\-\-list\fR
+.RS 4
+Lists all active inhibition locks instead of acquiring one\&.
+.RE
+.PP
+\fB\-\-no\-pager\fR
+.RS 4
+Do not pipe output into a pager\&.
+.RE
+.PP
+\fB\-\-no\-legend\fR
+.RS 4
+Do not print the legend, i\&.e\&. column headers and the footer with hints\&.
+.RE
+.PP
+\fB\-h\fR, \fB\-\-help\fR
+.RS 4
+Print a short help text and exit\&.
+.RE
+.PP
+\fB\-\-version\fR
+.RS 4
+Print a short version string and exit\&.
+.RE
+.SH "EXIT STATUS"
+.PP
+Returns the exit status of the executed program\&.
+.SH "EXAMPLE"
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+# systemd\-inhibit wodim foobar\&.iso
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+This burns the ISO image
+foobar\&.iso
+on a CD using
+\fBwodim\fR(1), and inhibits system sleeping, shutdown and idle while doing so\&.
+.SH "ENVIRONMENT"
+.PP
+\fI$SYSTEMD_LOG_LEVEL\fR
+.RS 4
+The maximum log level of emitted messages (messages with a higher log level, i\&.e\&. less important ones, will be suppressed)\&. Either one of (in order of decreasing importance)
+\fBemerg\fR,
+\fBalert\fR,
+\fBcrit\fR,
+\fBerr\fR,
+\fBwarning\fR,
+\fBnotice\fR,
+\fBinfo\fR,
+\fBdebug\fR, or an integer in the range 0\&...7\&. See
+\fBsyslog\fR(3)
+for more information\&.
+.RE
+.PP
+\fI$SYSTEMD_LOG_COLOR\fR
+.RS 4
+A boolean\&. If true, messages written to the tty will be colored according to priority\&.
+.sp
+This setting is only useful when messages are written directly to the terminal, because
+\fBjournalctl\fR(1)
+and other tools that display logs will color messages based on the log level on their own\&.
+.RE
+.PP
+\fI$SYSTEMD_LOG_TIME\fR
+.RS 4
+A boolean\&. If true, console log messages will be prefixed with a timestamp\&.
+.sp
+This setting is only useful when messages are written directly to the terminal or a file, because
+\fBjournalctl\fR(1)
+and other tools that display logs will attach timestamps based on the entry metadata on their own\&.
+.RE
+.PP
+\fI$SYSTEMD_LOG_LOCATION\fR
+.RS 4
+A boolean\&. If true, messages will be prefixed with a filename and line number in the source code where the message originates\&.
+.sp
+Note that the log location is often attached as metadata to journal entries anyway\&. Including it directly in the message text can nevertheless be convenient when debugging programs\&.
+.RE
+.PP
+\fI$SYSTEMD_LOG_TID\fR
+.RS 4
+A boolean\&. If true, messages will be prefixed with the current numerical thread ID (TID)\&.
+.sp
+Note that the this information is attached as metadata to journal entries anyway\&. Including it directly in the message text can nevertheless be convenient when debugging programs\&.
+.RE
+.PP
+\fI$SYSTEMD_LOG_TARGET\fR
+.RS 4
+The destination for log messages\&. One of
+\fBconsole\fR
+(log to the attached tty),
+\fBconsole\-prefixed\fR
+(log to the attached tty but with prefixes encoding the log level and "facility", see
+\fBsyslog\fR(3),
+\fBkmsg\fR
+(log to the kernel circular log buffer),
+\fBjournal\fR
+(log to the journal),
+\fBjournal\-or\-kmsg\fR
+(log to the journal if available, and to kmsg otherwise),
+\fBauto\fR
+(determine the appropriate log target automatically, the default),
+\fBnull\fR
+(disable log output)\&.
+.RE
+.PP
+\fI$SYSTEMD_LOG_RATELIMIT_KMSG\fR
+.RS 4
+Whether to ratelimit kmsg or not\&. Takes a boolean\&. Defaults to
+"true"\&. If disabled, systemd will not ratelimit messages written to kmsg\&.
+.RE
+.PP
+\fI$SYSTEMD_PAGER\fR
+.RS 4
+Pager to use when
+\fB\-\-no\-pager\fR
+is not given; overrides
+\fI$PAGER\fR\&. If neither
+\fI$SYSTEMD_PAGER\fR
+nor
+\fI$PAGER\fR
+are set, a set of well\-known pager implementations are tried in turn, including
+\fBless\fR(1)
+and
+\fBmore\fR(1), until one is found\&. If no pager implementation is discovered no pager is invoked\&. Setting this environment variable to an empty string or the value
+"cat"
+is equivalent to passing
+\fB\-\-no\-pager\fR\&.
+.sp
+Note: if
+\fI$SYSTEMD_PAGERSECURE\fR
+is not set,
+\fI$SYSTEMD_PAGER\fR
+(as well as
+\fI$PAGER\fR) will be silently ignored\&.
+.RE
+.PP
+\fI$SYSTEMD_LESS\fR
+.RS 4
+Override the options passed to
+\fBless\fR
+(by default
+"FRSXMK")\&.
+.sp
+Users might want to change two options in particular:
+.PP
+\fBK\fR
+.RS 4
+This option instructs the pager to exit immediately when
+Ctrl+C
+is pressed\&. To allow
+\fBless\fR
+to handle
+Ctrl+C
+itself to switch back to the pager command prompt, unset this option\&.
+.sp
+If the value of
+\fI$SYSTEMD_LESS\fR
+does not include
+"K", and the pager that is invoked is
+\fBless\fR,
+Ctrl+C
+will be ignored by the executable, and needs to be handled by the pager\&.
+.RE
+.PP
+\fBX\fR
+.RS 4
+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\&.
+.RE
+.sp
+See
+\fBless\fR(1)
+for more discussion\&.
+.RE
+.PP
+\fI$SYSTEMD_LESSCHARSET\fR
+.RS 4
+Override the charset passed to
+\fBless\fR
+(by default
+"utf\-8", if the invoking terminal is determined to be UTF\-8 compatible)\&.
+.RE
+.PP
+\fI$SYSTEMD_PAGERSECURE\fR
+.RS 4
+Takes a boolean argument\&. When true, the "secure" mode of the pager is enabled; if false, disabled\&. If
+\fI$SYSTEMD_PAGERSECURE\fR
+is not set at all, secure mode is enabled if the effective UID is not the same as the owner of the login session, see
+\fBgeteuid\fR(2)
+and
+\fBsd_pid_get_owner_uid\fR(3)\&. In secure mode,
+\fBLESSSECURE=1\fR
+will be set when invoking the pager, and the pager shall disable commands that open or create new files or start new subprocesses\&. When
+\fI$SYSTEMD_PAGERSECURE\fR
+is not set at all, pagers which are not known to implement secure mode will not be used\&. (Currently only
+\fBless\fR(1)
+implements secure mode\&.)
+.sp
+Note: when commands are invoked with elevated privileges, for example under
+\fBsudo\fR(8)
+or
+\fBpkexec\fR(1), care must be taken to ensure that unintended interactive features are not enabled\&. "Secure" mode for the pager may be enabled automatically as describe above\&. Setting
+\fISYSTEMD_PAGERSECURE=0\fR
+or not removing it from the inherited environment allows the user to invoke arbitrary commands\&. Note that if the
+\fI$SYSTEMD_PAGER\fR
+or
+\fI$PAGER\fR
+variables are to be honoured,
+\fI$SYSTEMD_PAGERSECURE\fR
+must be set too\&. It might be reasonable to completely disable the pager using
+\fB\-\-no\-pager\fR
+instead\&.
+.RE
+.PP
+\fI$SYSTEMD_COLORS\fR
+.RS 4
+Takes a boolean argument\&. When true,
+\fBsystemd\fR
+and related utilities will use colors in their output, otherwise the output will be monochrome\&. Additionally, the variable can take one of the following special values:
+"16",
+"256"
+to restrict the use of colors to the base 16 or 256 ANSI colors, respectively\&. This can be specified to override the automatic decision based on
+\fI$TERM\fR
+and what the console is connected to\&.
+.RE
+.PP
+\fI$SYSTEMD_URLIFY\fR
+.RS 4
+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
+\fBsystemd\fR
+makes based on
+\fI$TERM\fR
+and other conditions\&.
