So I've been using the command "poweroff" to shut down my Linux system, tried searching only if this is safe or not, mostly people just speak of "shutdown -h now" or something like that. So my question is: Is it safe to shut down Linux using the "poweroff" command?
When called with --force or when in runlevel 0 or 6, this tool invokes the reboot(2) system call itself and directly reboots the system. Otherwise this simply invokes the shutdown(8) tool with the appropriate arguments.
haltinstead, way shorter!
