Unix "look" Command "File too large" Error Message
I am trying to find lines in a text file larger than 3 Gb that start with a given string. My command looks like this:

$ look "string" "/home/patrick/filename.txt"


However, this gives me the following message:

"look: /home/patrick/filename.txt: File too large"


So, I have two questions.
1. How can I make this work with the "look" command and not any other commands such as "grep"?
2. If I were to use "grep", would it take longer than using "look", provided that I can somehow get "look" to work on this large file.

Thanks!
