The toolsets have also grown and changed. There's now a poweroff command, not present in s operating systems because the Central Processing Units on most contemporary machines had no way of controlling their power supplies. This flattening has brought us to the point where halt and shutdown are mostly the same. But the exact details vary from toolset to toolset, and the mechanics of each toolset are all slightly different.

It has also brought us to the slightly embarrassing position where this command set has become so festooned with compatibility options that it now allows people to give computers self-contradictory instructions like reboot --halt and poweroff --reboot , as I noted in the manual page for the nosh halt , fasthalt , reboot , fastboot , and poweroff commands. It's actually systemd's own systemctl program. It has several command line parsers for the various command line syntaxes of those commands, as well as its own, but after that largely funnels into one code path internally.
There's no difference between using halt and its command options to trigger an action and using shutdown and its command options to trigger the same action. Option-less shutdown now is the same as poweroff. The BSDs largely retain their s semantics. Whereas shutdown and poweroff , also one single program, do all of the considerate things like scheduled shutdown, writing wall messages, logging actions, disabling login, and so forth.
On all of them, option-less shutdown now is not equivalent to any of halt , reboot , or poweroff. It transitions to the BSD single user mode , from which one can transition back to multi-user mode. In the nosh system management toolset, halt , fasthalt , poweroff , fastpoweroff , reboot , and fastboot are all one program. It's a backwards compatibility shim that normally simply chains to shutdown , the opposite of received wisdom. The --force option makes it chain to system-control instead. Like with nosh, in the upstart system management toolset the opposite of received BSD wisdom applies.
So, again, there's no difference absent --force between the halt command and and shutdown command with the equivalent option in this toolset. Also again, option-less shutdown now which none of halt , reboot , or poweroff can end up invoking as they all set options brings the system into single user mode rather than shutting it down.
Again, in this toolset the opposite of received BSD wisdom applies and halt and reboot simply chain to shutdown — unless the system is already in the poweroff or halt "run-levels", in which case these commands actually enact the final system state change. So, again, there's no difference unless the system is already largely shut down between halt and shutdown because the former just invokes the latter.
And yes, again, option-less shutdown now which none of halt , reboot , or poweroff can end up invoking as they all set options brings the system into single user mode rather than shutting it down.

On Centos and I expec other modern Linux halt calls shutdown providing you're not at runlevel 0 or 6 so your system will be shutdown cleanly. On Solaris 10 halt is more brutal, it just flushes the disk caches and powers off the system - no attempt is made to run any scripts or shutdown smf facilities.
In linux, "halt" and "reboot" are aliases of the shutdown command -- shutdown -h and shutdown -r respectively. Bareword shutdown generally assumes -h. Sign up to join this community. The best answers are voted up and rise to the top.
