Look up rehash on the csh man page :
     rehash
          Causes the internal hash table of the contents of the
          directories in the _p_a_t_h variable to be recomputed.
          This is needed if new commands are added to directories
          in the _p_a_t_h 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 system directories.
Hope this helps.
