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.
