assuming you're in the target directory
Code:
  1. grep -r "Exchange - changes to NASDAQ" ./*
Copy Code
But it has to be that text EXACTLY that string, caps included. If you want case-insensitivity add a -i
grep is incredibly powerful and useful when you use regular expressions, and learning how to use them is highly reccommended. Damn near anything you can do on *nix can benefit for regexps.

Looks like someone beat me to it. However, one more word for you. I also suggest getting used to working with man pages. These are manuals on the different commands, applications, and even development resources available. To bring up a man page on grep, type in the following at the prompt.
Code:
  1. man grep
Copy Code
You will see a full screen page in your shell describing the grep syntax. When I have more time I might put together a complete tutorial on how to interpret man pages. However, an excellent way to learn how man works is:
Code:
  1. man man
Copy Code
