+unhash [ -adfms ] name ...
+       Remove the element named name from an internal hash table.   The
+       default  is remove elements from the command hash table.  The -a
+       option causes unhash to remove regular or global  aliases;  note
+       when  removing a global aliases that the argument must be quoted
+       to prevent it from being expanded before  being  passed  to  the
+       command.   The -s option causes unhash to remove suffix aliases.
+       The -f option causes unhash to remove shell functions.   The  -d
+       options  causes  unhash  to remove named directories.  If the -m
+       flag is given the arguments are taken  as  patterns  (should  be
+       quoted)  and  all  elements of the corresponding hash table with
+       matching names will be removed.
+
+unalias [ -ams ] name ...
+       Removes  aliases.  This command works the same as unhash -a, ex-
+       cept that the -a option removes all regular or  global  aliases,
+       or  with  -s  all suffix aliases: in this case no name arguments
+       may appear.  The options -m (remove by pattern) and  -s  without
+       -a (remove listed suffix aliases) behave as for unhash -a.  Note
+       that the meaning of -a is different between unalias and unhash.
+
+unfunction
+       Same as unhash -f.
