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

Answer 1

I am fascinated by how simple grep makes it with 'rl':

grep -rl 'pattern_to_find' /path/where/to/find

-r to recursively find a file / directory inside directories..
-l to list files matching the 'pattern'

Use '-r' without 'l' to see the file names followed by text in which the pattern is found!

grep -r 'pattern_to_find' /path/where/to/find

It works just perfect...
