Re: shutdown command?

i find that "poweroff" works a little better because it will stop all of your daemons and do other good shutting down things

Re: shutdown command?

Well, to quote the halt-manpage:

If halt or reboot is called when the system is not in runlevel 0 or 6, in other words when it's running normally, shutdown will be invoked instead (with the -h or -r flag). For more info see the shutdown(8) manpage.

Thus, if you are using your computer in any normal and sane way, halt just calls shutdown so there is no difference
/sbin/poweroff is a symlink to halt, so there is no difference either.

In other words, there is no better one, all are alike for almost all use-cases.
halt does differ when it is called from runlevels 0 and 6, but you can read how in the manpage

Re: shutdown command?

The recommended method to shutdown, reboot and switch to single user mode is to run shutdown command. It does some fancy things like broadcasting shutdown message to all currently logged users, scheduling real shutdown, enforcing fsck on next boot.
