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 el-
       ements  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 corresponding hash table matching these
       patterns are enabled.  Enabled objects can be disabled with the dis-
       able 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  EX-
       TENDED_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'.
