enable [ -afmprs ] name ...
       Enable the named hash table elements, presumably disabled earlier
       with disable.  The default is to enable builtin commands.  The -a
       option causes enable to act on regular or global aliases.  The -s
       option  causes  enable  to  act on suffix aliases.  The -f option
       causes enable to act on shell functions.  The  -r  option  causes
       enable  to  act on reserved words.  Without arguments all enabled
       hash  table  elements  from  the  corresponding  hash  table  are
       printed.   With  the  -m flag the arguments are taken as patterns
       (should be quoted) and all hash table elements  from  the  corre-
       sponding hash table matching these patterns are enabled.  Enabled
       objects can be disabled with the disable builtin command.

       enable -p reenables patterns disabled with disable -p.  Note that
       it  does  not  override globbing options; for example, `enable -p
       "~"' does not cause the pattern character ~ to be  active  unless
       the  EXTENDED_GLOB  option  is  also set.  To enable all possible
       patterns (so that they may be individually disabled with  disable
       -p), use `setopt EXTENDED_GLOB KSH_GLOB NO_SH_GLOB'.
