Syntax
builtin shell-builtin [arguments]
This is useful when defining a function whose name is the same as a shell builtin, retaining the functionality of the builtin within the function. The cd builtin is commonly redefined this way.
The return status is false if shell-builtin is not a shell builtin command.
builtin is itself a builtin command in both bash and Zsh.
Run the builtin command ls:
$ builtin ls
Local man page: builtin - Command line help page on your local machine.
