enable: Linux Commands HowTo
enable: Enable and disable builtin shell commands
Enable and disable builtin shell commands.
Syntax
enable [-n] [-p] [-f filename] [-ads] [name ...]
Options
-a list each builtin with an indication of whether or not
it is enabled.
-d Delete a builtin loaded with `-f?.
-f load the new builtin command name from shared object filename,
on systems that support dynamic loading.
-n Disable the names listed, otherwise names are enabled.
-p Print a list of shell builtins, default if no name arguments appear
With no other arguments, the list consists of all enabled shell builtins.
-s Restrict to enable only POSIX special builtins
Disabling a builtin allows a disk command which has the same
name as a shell builtin to be executed without specifying a full pathname, even
though the shell normally searches for builtins before disk commands.
For example, to use the test binary found via $PATH
instead of the shell builtin version, type `enable -n test?.
If there are no options, a list of the shell builtins is displayed.
If `-s? is used with `-f?, the new builtin becomes a special builtin.
The return status is zero unless a name is not a shell builtin or there
is an error loading a new builtin from a shared object.
You see things; and you say ?Why?? But I dream things that never were; and
I say ?why not?? - George
