builtin help enable

enable: enable [-a] [-dnps] [-f filename] [name ...]
    Enable and disable shell builtins.

    Enables and disables builtin shell commands.  Disabling allows you to
    execute a disk command which has the same name as a shell builtin
    without using a full pathname.

    Options:
      -a        print a list of builtins showing whether or not each is enabled
      -n        disable each NAME or display a list of disabled builtins
      -p        print the list of builtins in a reusable format
      -s        print only the names of Posix `special' builtins

    Options controlling dynamic loading:
      -f        Load builtin NAME from shared object FILENAME
      -d        Remove a builtin loaded with -f

    Without options, each NAME is enabled.

    To use the `test' found in $PATH instead of the shell builtin
    version, type `enable -n test'.

    Exit Status:
    Returns success unless NAME is not a shell builtin or an error occurs.
