It depends what you're trying to do. Problems can arise because the 
"command" might be an alias, built-in, function, etc. and the correct 
thing to do is to report this (or if you're trying to parse the output 
e.g. in a script, your script should be prepared to handle this).

That said, some combination of inspecting the -p, -P and/or -t options 
will probably get you there. I'd strongly encourage you to read the 
output of 'help type' :-). 'type' with no options is mainly intended for 
humans to read.
