cd()

int cd	(	int	nargs,
		char **	args )

Change the shell working directory.

If no path is provided, changes the current directory to /.

echo()

int echo	(	int	nargs,
		char **	args )

Write arguments to the standard output.

Display the ARGs, separated by a single space character and followed by a newline, on the standard output.

Options:

• -c - separate arguments with commas
• -n - no newline at the end
• -l - format output as a list

int pwd	(	int	nargs,
		char **	args )

• -P - resolves symlinks to get the current working directory.
