Comments on: ‘Shutdown’ versus ‘poweroff’ versus ‘halt’ on Ubuntu server http://k3rb.com/blog/2009/12/shutdown-versus-poweroff-versus-halt-on-ubuntu-server/ Sat, 14 Aug 2010 15:58:08 +0000 http://wordpress.org/?v=2.9.1 hourly 1 By: Kerberos http://k3rb.com/blog/2009/12/shutdown-versus-poweroff-versus-halt-on-ubuntu-server/comment-page-1/#comment-863 Kerberos Sat, 14 Aug 2010 15:58:08 +0000 http://k3rb.com/blog/?p=120#comment-863 True. So here' the explanation for that. From the <strong>man shutdown</strong> entry: -h Requests that the system be either halted or powered off after it has been brought down, with the choice as to which left up to the system. -H Requests that the system be halted after it has been brought down. This means that <strong>shutdown -H</strong> does not actually power the server off but puts the server in a state where it can be safely powered off by the admin. By comparion, <strong>shutdown -h</strong> may actually power the server off entirely if the system supports that. True. So here’ the explanation for that. From the man shutdown entry:

-h Requests that the system be either halted or powered off after
it has been brought down, with the choice as to which left up
to the system.

-H Requests that the system be halted after it has been brought
down.

This means that shutdown -H does not actually power the server off but puts the server in a state where it can be safely powered off by the admin. By comparion, shutdown -h may actually power the server off entirely if the system supports that.
