rc.shutdown —
command script run at system shutdown
DESCRIPTION
When the system is administratively shut down using either the
reboot(8)
or
halt(8)
command,
rc(8)
is invoked with the argument
“shutdown”,
which checks for the existence of a
/etc/rc.shutdown
script to run before halting the system.
This script, like
rc.local(8),
is entirely for commands added by the system administrator.
The
rc.shutdown
script is also executed by
init(8)
if a keyboard-requested halt is issued (for architectures that support this).
If
rc.shutdown
sets the variable
powerdown
to
“YES”,
halt(8)
will attempt to power down the machine after it has halted.
