I read a forum post some time ago (unfortunately I don’t have the link any more), that instructed me to invoke “reboot -h now” in Bash on a Raspberry Pi running the Unix-based Raspbian operating system.
It is supposed to reboot the system immediately.
What caught my eye though, was the -h switch.
There is no mention in the man page for the reboot function and I can’t find anything about the switch on the Internet.
Since invoking the shutdown function together with the switch -h does not throw any errors, I have to assume, that the associated daemon (I believe it’s systemd) does know the switch, making me conclude that it might be a deprecated feature, which is by default ignored today since it isn’t needed any longer.
I also have to mention, that since I only used Raspberry Pi’s with Linux up until now, I have no idea, whether this might even be a Raspberry-specific argument.
What is that specific switch supposed to do?
