Question

How can I grep out a particular line from a file in a folder.

Basically I have a folder /my/cool/folder/myfile.txt

I know it has line: I am cool lkasjdfaksldfj

How can I grep on that file so the line starting with I am cool .... shows on the terminal?

$ grep "^I am cool lkasjdfaksldfj" /my/cool/folder/myfile.txt

Also:

$ man grep

It'll do ya good.
