There are lots of totally different suggestions and methods on Linux that may actually enhance your life and productiveness. One such trick is studying find out how to schedule shut down on Linux PC.
On this information, we’ll go over find out how to schedule any Linux PC in order that it routinely powers off on a schedule. Moreover, we’ll cowl find out how to make use of the helpful rtcwake software for computerized PC wakeup!
Shutdown Software
Powering off Linux routinely works greatest with the built-in shutdown software. The shutdown program is included in all Linux distributions routinely, so there isn’t a must exit set up it. Utilizing it’s fairly easy and operates primarily based on 24-hr time.
Observe: unsure how 24-hr time works? Use this free conversion calculation tool.
Powering a Linux system on or off requires root privileges. Shutdown won’t work accurately with no root shell. To acquire root, open up a terminal and log into the basis consumer with su. Alternatively, if su doesn’t work, strive sudo -s.
su -
or
sudo -s
With root, the shutdown command now works. To flip off your Linux PC instantly, do:
shutdown -P now
Alternatively, to schedule a shutdown at a sure time, exchange now with a sure timeframe. On this instance, we’ll set Linux to show itself off at precisely 19:25 Hrs (07:25 PM).
shutdown -P 19:25
At any time, a scheduled shutdown command will be canceled, utilizing the c flag. Cancel a shutdown with:
shutdown -c
Reboot With Shutdown Software
Utilizing the shutdown command to routinely energy off a Linux PC at a set time is helpful. Nonetheless, regardless of its title, shutdown is able to rather more. One of many extra helpful options of this command is the “restart” flag. With it, the command will reboot your Linux PC on a schedule.
Utilizing the r flag to schedule a restart with shutdown works identically to how the P flag works. Merely write out the command, specify a time, and use the flag:
shutdown -r 19:25
As at all times, to disable the reboot command, do shutdown -c.
Schedule Wakeups
Rtcwake is a software that lets customers droop their PC, and schedule it to wake again up at a later time. In contrast to shutdown, the rtcwake command can use several types of time schedules. Particularly, it really works with each seconds and UTC (24 HR) time.
This software has lots of totally different settings and options. To get essentially the most out of rtcwake, save the command cheatsheet to a textual content file for later studying.

Droop To RAM And Wake
A well-liked means of sleeping a PC is to droop it to RAM. Many individuals go this route relatively than suspending to disk as suspending to RAM affords superior energy financial savings on laptops. With the rtcwake software, one of these suspending will be automated. To schedule your Linux PC to routinely droop to RAM and get up 8 hrs later, enter the next instructions.
Observe: the RTCwake software can use each seconds and UTC time. For extra exact wakeups, it’s best to use seconds.
su -
or
sudo -s rtcwake -m mem -s 28800
Droop To Disk And wake
Choose to droop to Disk once you put your Linux PC to sleep? Why not schedule it with rtcwake! Achieve a root shell and do the next to droop to disk for 12 hrs.
rtcwake -m disk -s 43200
Droop And Different Operations
Computerized sleep and wakeup is fairly helpful, however what about launching packages proper after wakeup? Fortunately, because of the best way Linux and UNIX work, it’s simple to pipe rtcwake into different instructions. For instance, to launch Libre Workplace immediately after rtcwake comes again from droop, run this command.
Observe: when piping different instructions with rtcwake, it’s greatest to make use of sudo, in any other case packages or scripts could open with the improper consumer.
sudo rtcwake -m mem -s 28800 && libreoffice
Including && tells the Bash immediate to do one operation AND one other, and so forth. For instance, to launch a number of packages after getting back from droop, strive:
sudo rtcwake -m mem -s 2800 && libreoffice && firefox && gnome-terminal && gimp
Don’t Droop However Wake
The rtcwake software usually instantly suspends, solely to get up later. When you’d wish to droop your Linux PC once you see match, however schedule a wakeup, you’ll must make use of the no function. Utilizing no tells rtcwake to not droop, however to get up on the set schedule.
Utilizing the no flag with rtcwake means there isn’t a must specify the kind of suspension, because the system assumes the consumer will do it manually later. As a substitute, simply specify when to get up.
su -
or
sudo -s rtcwake -m no -s 43200
