Help using grep

So I've got a text document I want to pull lines from in order of date. I've got every line starting with //10-20-11\\ (or whatever the date happens to be). Can I do this with grep, and if so how?

What the fuck shitheads..

man grep

Anybody? Maybe the image board guys will know something

The command would be:
more <filename> | grep <specific text>

grep '//10-20-11\\\\' <filename> | sort -nt '-' -k 3 -k 2 -k 1


grep filters, sort sorts. backslashes have to be escaped by prepending backslashes. see man sort for what the options -n -t and -k do.
