unicorn:~$ help pwd
pwd: pwd [-LP]
    Print the name of the current working directory.
    
    Options:
      -L	print the value of $PWD if it names the current working
    		directory
      -P	print the physical directory, without any symbolic links
    
    By default, `pwd' behaves as if `-L' were specified.
    [...]

Of course, this is all a big tangent from the original request.
