builtin [shell-builtin [arg ...]]
Execute the specified shell builtin, passing it args, and return its exit status. This is useful when you wish to define a shell function with the same name as a shell builtin, retaining the functionality of the builtin within the function.
The return status is non-zero if shell-builtin is not a shell builtin command.
Exit Status: Returns the exit status of SHELL-BUILTIN, or false if SHELL-BUILTIN is not a shell builtin.
