uls's Issues

Implement sorting flags

• -f - Output is not sorted. This option turns on the -a option;
• -t - Sorting by last modified;
• -c - Use time when file status was last changed for sorting (-t) or long printing (-l);
• -u - Use time of last access, instead of last modification of the file for sorting (-t) or long printing (-l);
• -U - Use time of file creation, instead of last modification for sorting (-t) or long output (-l);
• -r - Reverse the order of the sort to get reverse lexicographical order or the oldest entries first (or largest files last, if combined with sort by size;
• -S - Sort files by size;

Refactor get_entries_in_directory

Implement some of the flags that represent output modes

• -l - Long output
• -C - Force multi-column output; this is the default when output is to a terminal;
• -1 - (The numeric digit ``one''.) Force output to be one entry per line. This is the default when output is not to a terminal;
• -m - Stream output format; list files across the page, separated by commas.
• -x - The same as -C, except that the multi-column output is produced with entries sorted across, rather than down, the columns.

Add flags of type "elements selection"

Flags:

• -A - List all entries except for . and ..;
• -a - Include directory entries whose names begin with a dot (.);
• -R - Recursively list subdirectories encountered;
• -d - directories are listed as plain files;

By default, the arguments have the current directory (.) if there are no files.

Implement -G flag

This flag enables colorized output.

Add output "usage"

When the user enters an invalid flag, the program must print an error (for example: ./uls -Q):

uls: illegal option -- Q
usage: uls [-l] [file ...]

Implement -l flag

• -l - List in long format. If the output is to a terminal, a total sum for all the file sizes is output on a line before the long listing;
• -g - Like -l but without owner;
• -o - Like -l but without group information;
• -e - Print the Access Control List (ACL) associated with the file, if present, in long (-l) output;
• -@ - Display extended attribute keys and sizes in long (-l) output;
• -c - Use time when file status was last changed for sorting (-t) or long printing (-l);
• -e - Print the Access Control List (ACL) associated with the file, if present, in long (-l) output;
• -T - When used with the -l (lowercase letter ``ell'') option, display complete time information for the file, including month, day, hour, minute, second, and year;
• -h - Sizes are human readable.

Easy flag for dessert

-p - Write a slash (`/') after each filename if that file is a directory;
