![]() ![]() ![]() Needless to say that the reference time and timezone is the system time itself.įive minutes before the scheduled shutdown, the system won’t allow any login activity. Which means a new user cannot log on to the system within five minutes of the scheduled shutdown.ģ. There is a separate reboot command but you don’t need to learn a new command just for rebooting the system. You can use the Linux shutdown command for rebooting as well. To reboot a Linux system using the shutdown command, use the -r option. The behavior is the same as the regular shutdown command. ![]() It’s just that instead of a shutdown, the system will be restarted. So, if you used shutdown -r without any time argument, it will schedule a reboot after one minute. You can schedule reboots the same way you did with shutdown. You can also reboot the system immediately with shutdown command: sudo shutdown -r now 4. If you are in a multi-user environment and there are several users logged on the system, you can send them a custom broadcast message with the shutdown command.īy default, all the logged users will receive a notification about scheduled shutdown and its time. You can customize the broadcast message in the shutdown command itself: sudo shutdown 16:00 "systems will be shutdown for hardware upgrade, please save your work"įun Stuff: You can use the shutdown command with -k option to initiate a ‘fake shutdown’. It won’t shut down the system but the broadcast message will be sent to all logged on users. If you scheduled a shutdown, you don’t have to live with it. You can always cancel a shutdown with option -c. Sudo shutdown -cĪnd if you had broadcasted a messaged about the scheduled shutdown, as a good sysadmin, you might also want to notify other users about cancelling the scheduled shutdown. sudo shutdown -c "planned shutdown has been cancelled" Bonus: Filesystem check at reboot You can force a filesystem check at the next reboot with the -F option. So if you use it with any of the above mentioned options of shutdown command, it will do a filesystem check when the system starts again. Similarly, you can use the flag -f to skip the filesystem check. Halt (option -H): terminates all processes and shuts down the cpu. Power off (option -P): Pretty much like halt but it also turns off the unit itself (lights and everything on the system). Historically, the earlier computers used to halt the system and then print a message like “it’s ok to power off now” and then the computers were turned off through physical switches. These days, halt should automatically power off the system thanks to ACPI. These were the most common and the most useful examples of the Linux shutdown command. I hope you have learned how to shut down a Linux system via command line. #TERMINAL MAC SHUTDOWN COMMAND IN THE FUTURE HOW TO# You might also like reading about the less command usage or browse through the list of Linux commands we have covered so far.
