Is there a way to find a specific word in all files/folders in Linux?

Question

I usually use grep word * while being in a folder which includes files that have that word. But in this folder i also have folders which under them there are files that have that word, what is the correct command for this matter please?

Thanks

Answer 1

find . -type f | xargs grep -l "search-pattern" 

or

grep -R "search pattern" *

Answer 2

There's a recursive option to grep:

grep -R word *

You can replace "*" with a full path to a directory that you want to look at as using a wildcard will search for the word "word" in current directory.
