Same thing, just tcsh. man tcsh ->
rehash Causes the internal hash table of the contents of
the directories in the path variable to be recom
puted. This is needed if new commands are added
to directories in path while you are logged in.
This should only be necessary if you add commands
to one of your own directories, or if a systems
programmer changes the contents of one of the sys
tem directories. Also flushes the cache of home
directories built by tilde expansion.
Gruss,
Jens.
