Grep Flags – The Good Stuff
>The -I flag only considers text files. This radically speeds up recursive greps.
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.

Ask HN: Is there a GUI for bash shell?

Try / Ripgrep in Y Minutes
A bit of an aside, but I really like "guides to things we otherwise take for granted". So few man pages are built around example use cases, but those are often what make the case for a tool!
A similar spirit to projects like https://github.com/tldr-pages/tldr/ , but this has a lot more useful detail.
The ripgrep author has a blog post on performance and benchmarking that is an interesting read in itself: https://blog.burntsushi.net/ripgrep/

Should you add screenshots to documentation?
Looks like bro pages is archived and they recommend https://github.com/tldr-pages/tldr or https://github.com/cheat/cheat
