What is the difference between these commands for bringing down a Linux server?
3 answers
I just realized that /usr/bin/poweroff and /usr/bin/shutdown are symbolic link to systemctl, but I don't know how systemctl is being run.
so is there any difference between /usr/bin/poweroff and /usr/bin/shutdown?
EDIT: when I call any of these two programs, systemctl is being executed but I don't know what command/parameter is passed to systemctl.
when I type systemctl --helpthere are two options that may come into play
- halt Shut down and halt the system
- poweroff Shut down and power-off the system
but something tells me that both poweroff and shutdown are the same in here (I'm guessing)
I'm running Archlinux
linux shutdown systemctl

In most systems, every "shutdown" command is just a symlink to a common program/script
which changes its behaviour based on how (with which "name") is invoked.
So, poweroff does a kind of shutdown which powers off the machine (usually via ACPI APIs), too and it's equivalent to shutdown -hP, while shutdown
as a command is more generic and can do many thigs after "stopping" the OS, based on with which flags is called.
For example shutdown -r reboots the machine while shutdown -h just stops the OS (and the machine is still powered on, while not usable).

It's an oversimplification to say thatpoweroffis equivalent toshutdown -hP. It's equivalent to that in the van Smoorenburg toolset, but in the systemd toolset both the-hand-Poptions are the defaults anyway and it is equivalent to plainshutdown now. Thenowis important, by the way. unix.stackexchange.com/a/196471/5132 unix.stackexchange.com/a/465337/5132

right, but as far as I can see both programs are a symlink to systemctl, I don't see how systemctl is being used. What makes it interesting is that those flags mention here have not use with systemctl

nowis important because without it there is a difference. Pay close attention to the user manual of the systemd toolset.
