only. This command allows you to load new built-in commands into the shell at runtime from shared library files.
If no arguments are given,
prints all the built-in command names. With arguments, builtin
adds each name
as a new built-in command (like cd
). If the name
contains a slash, the newly-added built-in version is used only if a path search would otherwise have found a command of the same name. (This allows replacement of system commands with faster, built-in versions.) Otherwise, the built-in command is always found.
