This may not be a bug and may have come up before but I am puzzled:

The system in question is a VAX 4.3BSD.  I found several commands,
namely e, ex, mail, and grep, with duplicated entries in the standard
PATH directories.  The first three I can understand the intention.
But grep exists in both /bin and /usr/ucb with source files in the
corresponding areas.  The two source files look similar but not
identical.  My questions area: Why two "grep"?  And is there any
difference in their functions or speeds?
