I looked up the man page for grep. When reviewing the Treehouse course on navigating the shell, I saw there were ways to have the shell spit output back to you based on criteria using grep. That was pretty cool. But I have virtually no experience with regular expressions. Somehow I've always been able to avoid having to learn how to build regular expressions.

While reviewing the man page for grep didn't give me any info about regular expressions, it does tell me there are many ways of filtering out and emphasizing the parts of an output that I would like to see. The big question is whether it will be worth my while in the long run to learn regular expressions and grep.
