4	when you use the -l flag w/ ls, there will be a string of characters on the left for each file, which may look something like -rwxr-xr-x
5	the first character describes what the item is:
6	- = regular file
7	d = directory
8	b = special block file
9	c = special character file
10	l = symbolic link
11	p = named pipe special file
12	example: lrwxr-xr-x would be a symbolic link
13	the next 9 characters are 3 groups of 3 characters each, which tell the read/write/execute permissions for user, group, and other respectively:
14	r = read
15	w = write
16	x = execute
17	using the above example of lrwxr-xr-x, you would have symbolic link file, where the user can read, write and execute (rwx), and the group and others can read and execute (r-x)
