System function ls is recoded on this git repository.

From BSD General Commands Manual:

NAME
	ls -- list directory contents

SYNOPSIS
	ls [-ABCFGHLOPRSTUW@abcdefghiklmnopqrstuwx1] [file ...]

DESCRIPTION
	For each operand that names a file of a type other than directory, ls displays its name as well as any requested,
	associated information.  For each operand that names a file of type directory, ls displays the names of files con-
	tained within that directory, as well as any requested, associated information.

 	If no operands are given, the contents of the current directory are displayed.  If more than one operand is given,
 	non-directory operands are displayed first; directory and non-directory operands are sorted separately and in lexico-
	graphical order.

for more information search in BSD General Commands Manual.

However the synopsis of my ls is:

./ft_ls [-lRartufgds1] [file ...]

To compile a binary that will list directories you should do make. After what you can watch through any directory (if you have such permisions of course). To inititalise ft_ls you should write:

./ft_ls

That's it! Every option (such as -l or -a) is implemented due to the option of original ls, so u can watch how it works and compare with my function!

Additional info:

Makefile functions:

• make/make all - compiles a binary named ft_ls;
• make clean - removes every object file from obj directory;
• make fclean - the same as make clean + removes binary file ft_ls;
• make re - the same as make fclean + make.
