what i can think of it this command means substitue where you find a file beginning with http: followed by " and to save all the text on line until double quote is found .
-e "s/^http:\/\///"
https://www.unix.com becomes www.unix.com i.e. get rid of http://

-e "s/^\/\{2,5\}//"
Any line which starts with the one of the following
//
///
////
/////

will be removed.

-e "s/^\/$//"
Any line which starts and ends with a / will be removed. i.e. the line contains only a /

i dont know the rest and please clearify me if i am wrong trying to learn this scripting and vi editor. any help would be great.
Thanks
Any statement containg a : (colon) and text on either side of : (colon) will be removed. The | is a pipe. There might be some command after that.
