Is this a homework question?

Hi,

This is no homework job! im new to grep and i need a quick solution to extract data for a small task on hand.

Thx for the solution,

Okay... It just sounded a lot like a homework question I once had in my bash class some moons ago. I'm glad that it worked for you though. That's why we're here.

For future reference:will find in the html file only the part of the line that matches the regular expression. Since you were trying to find something that isn't part of another word or phrase (I.E. it's wrapped in tags or whitespaces) this works just fine... but I think you got that already.This will look for zero or more capital letters followed by a ".V". The backslash is to escape the period because it is a special character and escaping it tells grep that you're looking for a period and not any single character.Think of this as a separator... an OR if you will. It needs to be escaped as well.Same as before but with the TO extension.
