Builtin
Execute a builtin command. This is only useful when reimplementing a builtin but still need to call the original builtin within the function.
Caller
Cd
Change the current working directory to a new path. Can be a relative or absolute path, as well as the special . and .. directories.
Note the rules for tilde expansion when using the ~ symbol here.
cd - changes the current working directory to the previous working directory.
There is also special behavior around specifying nothing. cd is the same as cd ~.
