how to Shutting Down or Rebooting fedora Linux in command mode

Shutting Down or Rebooting Linux


Look at all these shutdown and reboot commands: shutdown, halt, init 0, poweroff, Ctrl-Alt-Delete, etc. What's the right one to use?


It doesn't matter all that much; use what suits you. Only root can use these commands to shut down:


# shutdown -h now






or:


# poweroff




or:


# halt




To shut down in six minutes:


# shutdown -h +6




shutdown sends a notification to all logged-in users. To make your own message, use:


# shutdown -h +6 "Time to stop working and start partying."




Console users will see:


Broadcast message from root (pts/6) Wed Aug 14 13:51:24 2003


Time to stop working and start partying.


The system is going DOWN for system halt in 6 minutes!




To cancel a shutdown as root, use:


# shutdown -c




To reboot, you can use:


# shutdown -r now




or:


# reboot




or press Ctrl-Alt-Delete. Any user can do this, unless you disable it in /etc/inittab.
