The first project in 42's Systems Branch.
The goal of this project is to recode some of MacOS's ls command functionality. The main behaviors this version must replicate are:
-R - Recursively list subdirectories encountered.
-a - Include all entries whose names begin with a ' . '.
-l - List in long format.
-r - Reverse the order of the sort to get reverse lexicographical order or the oldest entries first.
-t - Sort by time modified (most recently modified first) before sorting the operands by lexicographical order.
Note that the output mimics the output of ls -1, where instead of being spaced out according to the width of the terminal window, the output is listed instead.
Extra functionality added in includes:
-A - Include all entries whose names begin with a ' . ', excluding the "." and ".." directories.
-G - Prints with colors
-S - Sort by size.
-T - When used with -l, display complete time information, MMM DD HH:MM:SS YYYY.
-c - Use time when file status was last changed for sorting (-t) or long printing (-l).
-f - Does not sort output. This option automatically triggers the -a flag.
-n - Prints out the numerical identifier for any groups and owners. This option automatically triggers the -l flag;
-u - Use time of last access, instead of last modification of the file for sorting (-t) or long printing (-l).
To make the program, run make.
To use the program, run ./ft_ls with any of the above flags, used in any combination.
