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.

I just hate the syntax, systemctl start apache2 feels like dumb manager speak over service apache2 start.
But other then that I love how systemd has been for me.
How so? I like the systemctl syntax more, since it allows for starting/stopping many units at once. It also supports a much richer set of commons than service ever did.
it just feels like a manager decided the command should read like english, made the decision then went back to never entering a command again in the terminal again. every day, i get to decide, should i enter "systemctl restart problem_service" all again or hit up on the keyboard and and hold back, then rewrite over the previous status command. bit less work if the status/stop/start/restart bit was on the end like it used to be.
In BASH ALT+T will swap the last white spaced separated strings.. It's still annoying but makes "systemctl problem_server start/status/restart" a bit easier. CTRL+W will clear the current string to whitespace, so up arrow, ALT+T, CTRL+W, status, ALT+T, Enter.
The bit was on the end because it was an argument to the script specific to that program. Instead, the control is now at the start because it is an argument to systemctl itself. This removes the ability to define custom controls, but enables you to control many things at once.
Yeah,
command subcommand args.... Theserviceformat makes more sense when you're seeing it as "run this script to control this service". Thesystemctlformat makes more sense as a frontend subcommand to control systemd itself.Y'know, I felt that way to begin with and it certainly took a long time for my fingers to adjust, but I've grown to adjust to that.
And it's better - you can do: "systemctl restart Service1 Service2 Service3" Before, with "system Service1 restart" you could only action on service at a time.
Plus, it's linux, so you can set up aliases to change the order into anything you like, even carry on using the old muscle memory formats. (Although I don't encourage this if you intend working on multiple servers!)
systemctl start apache2 mysql haproxy
That is the reason.
