From what I have read . is for current director and the / represents directory.
So I have a file hello.c in order to run that file I have to type
./hello which is a compiled C program. If I put a space after the ./ I recieve ./ is a directory.
However if I use the cp command
cp /home/user1/file.c .
The file will be copied to current working directory where ./ is not needed.
Anyone shed some light on what exactly ./ used for.

will list files a, b, and c in reverse order thinking that -r was an option requesting reversed output sort order; the command
will list all files in the directory (including -r) in long format in reverse order. If you just want to see a long format listing of the file -r you can do that with either of the following commands:
