    Phoronix: Grep 3.7 Released To Fix "Extreme Performance Degradation"

    If you have noticed grep regressing performance-wise in recent releases, you may want to upgrade to GNU Grep 3.7 released this weekend as it fixes a nasty performance regression...

      There is also ripgrep, a grep tool written in Rust that is supposedly really fast.
      ripgrep recursively searches directories for a regex pattern while respecting your gitignore - GitHub - BurntSushi/ripgrep: ripgrep recursively searches directories for a regex pattern while respecting your gitignore

        I wonder if there are Gnu Grep alternatives.

        I wonder if there's a Grep equivalent for non-textual data.

        EDIT: I just found this

        Binary Grep. Contribute to clayne/bgrep development by creating an account on GitHub.


        In the previous article, I showed how to use the grep command, which is great at finding text files that contain a string or pattern. The idea of directly searching in a “grep-like” way is so useful that there are additional commands to let you search right into PDF documents and handle XML files more …


        ngrep, etc.

            Ubuntu 20.04 is still using v3.1 and the issue started in v3.5.

              Can you tell me why you thought it's worth mentioning that it's written in Rust?

                No, I can't, but maybe that is why it's so fast? You know a core concept of Rust is fearless concurrency, oh and zero-cost abstractions.

                  Because Rust is changing the world with better software!

                    In C/C++ something is correct when someone can use it correctly, but in Rust something is correct when someone can't use it incorrectly.
