To shut down Red Hat Enterprise Linux, the root user may issue
the /sbin/shutdown command. The shutdown man page has a complete list of options,
but the two most common uses are:
/sbin/shutdown -h now
/sbin/shutdown -r now
|
After shutting everything down, the -h
option halts the machine, and the -r
option reboots.
PAM console users can use the reboot
and halt commands to shut down the system
while in runlevels 1 through 5. For more information about PAM
console users, refer to Section 16.7
PAM and Device Ownership.
If the computer does not power itself down, be careful not to
turn off the computer until a message appears indicating that the
system is halted.
Failure to wait for this message can mean that not all the hard
drive partitions are unmounted, which can lead to file system
corruption.
