Example of location of a home directory

Although both joe and sarah are registered as users on their local UNIX system, they belong to different departments; joe is a postgrad student in artificial intelligence while sarah is Head of the Math Department. Their respective home directories might be:

    |		|
   /tmp	       /usr
        ---------------- ... ----
        |	|		|
       /ai	/biol		/math
        |			|
   ------------		-----------------
   |					|
/joe				     /staff

The full pathname to joe's home directory is /usr/ai/joe; that to sarah's is /usr/math/staff/sarah.
