  If we want to use timed shutdowns, for example, 5 minutes from now or at a specific time, and warn all logged-in users. Or you want to just shut down now with no frills.   Shut down immediately, with no notification to other logged-in users: $ shutdown -h now Shut down   in 10 minutes with notifications: $ shutdown -h +10 Shutdown scheduled for Tue 2021-11-09 11:04:43 IST, use 'shutdown -c' to cancel. Cancel the   shutdown: $ shutdown -c Create your own message: $ shutdown -h +6 "Time to watch trie Tree Technologies Youtube Channel" Rather than specifying minutes to shutdown, you may set a shutdown time in 24-hour hh:mm format. The following example shuts down the system at 11:20 P.M.: $ shutdown -h 23:20 Reboot: $ shutdown -r Halt the   system without powering off: $ shutdown -H  

 Use systemctl   commands to shut down and reboot your system.   Halt the   system and power off the machine: $ systemctl poweroff Halt the system   and power off the machine: $ systemctl shutdown Reboot your machine: $ systemctl reboot Halt the system without   powering off the machine: $ systemctl halt

  Git and GitHub are two completely different things. Let me quickly explain what is Git and what is GitHub and how they are actually related. Most popular definition of Git is following: Git is distributed version-control system, but this definition is actually too complicated, especially for beginners. Let me explain you what is Git in more simple words. Git allows you to track files in any folder called repository, and Git preserves history of all changes that you make with files in this repository. But how Git does that? How it stores all changes of all files in the folder? Under the hood, Git has its own, let's say, file structure, and every file is stored in a separate document, and every file has special hash, and that's why we can say that Git is simply persistent hash map and it stores keys and values; nothing else. Key is a hash and value is content of every file. Another important notice regarding Git, you can use it locally on your computer, even without internet an...
