Linux in a Nutshell, 6th Edition

Name

enable

Synopsis

enable [-adnps] [-f file] [command ...]

Enable or disable shell built-in commands. Disabling a built-in lets you use an external version of a command that would otherwise use a built-in version, such as echo or test.

Options

-a

For use with -p, print information about all built-in commands, disabled and enabled.

-d

Remove (delete) a built-in previously loaded with -f.

-f file

Load a new built-in command command from the shared library file file.

-n

Disable the named built-in commands.

-p

Print a list of enabled built-in commands.

-s

Print only the POSIX special built-in commands. When combined with -f, the new built-in command becomes a POSIX special built-in.
