Don't make a habit of doing so. It's not wise.

Root should always be aware of _where_ the commands are. Always use
full paths to the program, or only use programs in your PATH. Never
put "." in your PATH.

The reason to this is, that a malicious user could put often used
commands in his homedirectory. If the root-user unknowingly executes
one of these (fx by typing ls in a user-directory, while having "." in
PATH) - terrible things could happen.

Therefore use:

        /sbin/shutdown -r now
