1.5. Shutting Down
To shut down Red Hat 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 will
halt the machine, and the -r option will reboot.
Non-root users can use the reboot and
halt commands to shut down the system while in
runlevels 1 through 5. However, not all Linux operating systems support
If the computer does not power itself down, be careful not 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, and can lead to file system corruption.
