I use ripgrep when I need better speed. I've pretty much switched to ripgrep these days, but still use GNU grep when I'm answering questions on stackoverflow, reddit, etc.

>ABC flags

Good to also know about `--group-separator` and `--no-group-separator` when there are multiple non-contiguous matches. Helps to customize the separator or remove them altogether. Sadly, these options are still not explained in `man grep` on Ubunutu. You'll have to use `info grep` or the online manual to find them.

Options I use often that is not mentioned in the article:

* `-c` to count the number of matches

* `-F` for fixed string matching

* `-x` to match whole lines

* `-P` for PCRE (as mentioned in many comments here)

* `--color=auto` this is part of command name alias, so it is always used

I wrote a book as well on "GNU grep and ripgrep": https://github.com/learnbyexample/learn_gnugrep_ripgrep Free to read online.
