Synopsis
rehash
Recompute the internal hash table for the PATH
variable. Use rehash whenever a new command is
created during the current session. This allows the
PATH variable to locate and execute the command.
(If the new command resides in a directory not listed in
PATH, add this directory to
PATH before rehashing.) See also
unhash.
