enable [ -afmprs ] name ...
       Enable the named hash table elements, presumably  disabled  ear-
       lier  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  pat-
       terns  (should  be  quoted) and all hash table elements from the
       corresponding hash table matching these  patterns  are  enabled.
       Enabled  objects  can  be disabled with the disable builtin com-
       mand.

       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 un-
       less the EXTENDED_GLOB option is also set.  To enable all possi-
       ble patterns (so that they may  be  individually  disabled  with
       disable -p), use `setopt EXTENDED_GLOB KSH_GLOB NO_SH_GLOB'.
