If you execute <command> as root (better than using sudo) you can either
issue from the # prompt

command; shutdown -h now

that shuts down the machine either if <command> is successful or fails

while 

command && shutdown -h now

shuts down the machine only if <command> is successful. On the other hand

command || shutdown -h now

shuts down the machine only if <command> fails

If you don't run <command> as root you must either wait for <command> to
end (to type the password) or be sure that it completes before the
validity of the sudo password cache expires.
