Fixed typos, serial comma, and removed "either" as there were more
than two options. Also did an extra rename of "system-shutdown"
to "systemd-shutdown" that was forgotten in commit

<title>Description</title>
|
|
|
|
<para><command>systemd-inhibit</command> 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.</para>
|
|
|
|
<para>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.</para>
