Systemctl Command Examples in Linux
(itsfoss.com)
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Two additional commands I regularly use as a Sysadmin are
systemctl status
without any unit to list show the general system status (lists units that are running, units that are starting and failed units right at the top) And thensystemctl list-units --failed
To show me just the failed units and did deeper what the problem is.On a properly set up system I should quickly be able to ascertain if everything is "up and running" just by systemds status
You can also use
systemctl status $pid
to find out what service a process is from.This and
systemctl cat $unit
are my favorites.You can .... WHAT!?
Wow I did not know that. Incredibly helpful
Oooh. Thank you, I didn't know that.
You can skip
list-units
and just dosystemctl --failed
You can even drop the
list-units
and just usesystemctl --failed
Didn't know that. Thanks!
