.SH "NAME"

.SH "SYNOPSIS"

\fBsystemd\-inhibit \fR\fB[OPTIONS...]\fR\fB \-\-list\fR
.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, 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$SYSTEMD_PAGER\fR
.RS 4
Pager to use when
\fB\-\-no\-pager\fR
is not given; overrides
\fI$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\&.
.RE
.PP
\fI$SYSTEMD_LESS\fR
.RS 4
Override the options passed to
\fBless\fR
(by default
"FRSXMK")\&.
.sp
If the value of
\fI$SYSTEMD_LESS\fR
does not include
"K", and the pager that is invoked is
\fBless\fR,
Ctrl+C
will be ignored by the executable\&. This allows
\fBless\fR
to handle
Ctrl+C
itself\&.
.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
.SH "SEE ALSO"
.PP
