#####Mimic unix's ls function.

#####Grade (105/100) (105/119)*

Goals:

• Recode part of the ls function.
• "l" flag. (Long format)
• "R" flag. (Recursive folder exploration)
• "a" flag. (Show hidden files)
• "r" flag. (Reverse sort)
• "t" flag. (Sort by modification time)

Recommended bonuses:

• Handle multi-column output when "l" option is disabled
• Print Access Control List, and extented attributes with "l" option.
• "u" flag. (With "t": Use access time) (With "l": Show access time)
• "f" flag. (Do not sort)
• "g" flag. (Like "l", do not list file owner)
• "d" flag. (Treat all path arguments as files)
• "G" flag. (Colors)

My additions:

• "A" flag. (Like "a", but do not list . and .. entries)
• "B" flag. (Print numeric value for non-printable characters)
• "C" flag. (Force multi-colum printing when stdout is not a TTY)
• "F" flag. (Append indicator to file names "*/=@|%")
• "b" flag. (Like "B", but use C escape codes whenever possible)
• "h" flag. (Human readable sizes)
• "n" flag. (Numeric uid and gid)
• "o" flag. (Like "l", do not list group informations)
• "1" flag. (Single-column output when "l" option is disabled)
