Where do you run your ‘find’ command? And what are yo looking for? The way your command looks now, you are asking ‘find’ to look in the local sub-directory ‘httpdocs’, but you do not define what to look for.
You probably mean:
find ./ -name httpdocs -type d -print
First you specify where to look ( ./ ), then what you are looking for (-name …,
-type …) and then what to do with what you find (-print).
