Using the command “ls” options and arguments

ls has some interesting format which is very useful. Here are some arguments which you can use. For example, I like

$ ls - ltF

-a –all	All files include those with .
-l	Display results in long format
-r –reverse	Reverse order while sorting
-S	Sort results by file size
-t	Sort by modification time.
-F –classify	Append an indicator character to the end of each listed name
