Understanding systemd

Linux Basics Course
#1

Hello,

I have 2 questions.

First, I am facing issues understanding the concept of systemd in linux. What exactly is it and how does it work ?

Second, all through the lessons, it is not mentioned how each of the commands in the course runs on different linux distributions. Would you comment on both questions?

Thanks

  1. systemd is a sort of master program that launches and monitors other server programs when the system starts up. If you’re running a server program in Linux, odds are good that it’s being run under systemd’s control.
  2. Most of the commands you’ll study in this course run the same under most Linux distributions. So while we’re demonstrating them on Ubuntu, they’ll run pretty much the same on a RedHat flavored distribution, SUSE, or anything else.
