URGENT! Searching text file for specific text

Im trying to search my text file for specific text. I have an inputbox requesting the information from a user, and from that I want it to search my text file for the name. Example Tom Bernard T141 905-685-5655 6.0

Say if i want to search for the first name, Tom
I want to search from 0, to the firstspace
and return the whole text line that it comes along with

So if Tom is found display the line in which Tom is found

IF someone can help it would be appreciated. Im really stuck!
