How do I find all files containing specific text on Linux?

Answer 1

You can use ack. It is like grep for source code. You can scan your entire file system with it.

Just do:

ack 'text-to-find-here'

In your root directory.

You can also use regular expressions, specify the filetype, etc.

UPDATE

I just discovered The Silver Searcher, which is like ack but 3-5x faster than it and even ignores patterns from a .gitignore file.
