Enable and disable builtin shell commands
Syntax
enable [-adnps] [-f filename] [name ...]
Key
-f filename Load the new builtin command name from shared object filename,
on systems that support dynamic loading.
-d name Delete a builtin previously loaded with -f.
-n List all disabled builtins
-n name Each name is disabled; otherwise, names are enabled.
-a List all builtins with enabled/disabled state of each.
-p List all enabled builtins.
<no options> List all enabled builtins.
-s List only the 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.
Example
To use the test binary found via the PATH instead of the shell builtin version
$ enable -n test
To restore the builtin version:
$ enable test
The return value is 0 unless a name is not a shell builtin or there is an error loading a new builtin from a shared object.
