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 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.
