[CLUE-Tech] Why can't bash find vi?

[Timothy C. Klein]

Jed,
So this xterm was open before you changed any of this stuf with vi?  And
subsequent xterms work fine?  If that is the case, I would say that bash
is remembering where vi used to be.   Bash hashes previous directory
lookups in an internal data structure so that it does not have to look
up the location of the exec every time.  Try typing:
 
type vi

It should tell you where bash thinks it is.  If it says something like
(/bin/vi: hashed) that means it is stored in the internal data
structure, and will not be looked up again.  I don't remember if one
can clear that entry from the internal hash, but I would imagine one
could.
