how to grep out a particular line from a file

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?

Also:

$ man grep

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

If you want to search in all files in a folder

grep "^I am cool lkasjdfaksldfj" /my/cool/folder/*

If you want the string to be searched anywhere and not necessarily the beginning of line

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

Useless use of `cat`. – Teddy Mar 26 '10 at 08:41
Why limit yourself to a single process when you can use two?!?! ;) – EEAA Mar 26 '10 at 14:02
