If you are serious about working in a terminal, then I highly recommend learning modern replacements for the old tools.

In this case ripgrep (or rg) https://github.com/BurntSushi/ripgrep is phenomenal. Especially for searching recursively in a large directory tree it is unbelievably quicker than regular grep.

It won’t be installed on any random machine, so grep is still useful, but if you regularly need to text search in files then there are better tools.
