I was just wondering how to parse out the jpgs links from reddit wallpaper page following a commandline fu bash script,just for fun. The main problem is how to reject a match which matches beginning and end but by using .+? matches falsely in the middle.I know you can reject matching letters with [^ahi] type expression.But I dont know how to reject a string in the middle of a large amount of data. The following shows the problem match.
