I wrote a book on GNU grep and ripgrep, available for free this week

Hello!

I've just published my book on **GNU GREP and RIPGREP** and it is FREE to download this week! You can still pay if you wish :)

Get the e-book using either of these sites:

* https://gumroad.com/l/gnugrep_ripgrep
* https://leanpub.com/gnugrep_ripgrep

**Note** Please use a valid e-mail and save the mail you receive, you'll get free updates for future versions - notifications are opt-in. Both the links have suggested prices as default, so change them before purchase.

Code snippets and files are available on GitHub: https://github.com/learnbyexample/learn_gnugrep_ripgrep

This book covers features of `gnu grep` and `ripgrep` along with discussion on BRE/ERE/PCRE(2)/Rust `regular expressions`. Examples are used extensively, please follow along by typing them out. Exercises are also included to test your understanding.

Some of you might be familiar with my previous posts here for [Command Line Text Processing](https://github.com/learnbyexample/Command-line-text-processing) repo. This book is based on the `grep` chapter - edited to add more denoscriptions, better examples, exercises, etc. Also, I took the plunge and checked out `ripgrep` while working on this book. I'd assumed it would be similar to `gnu grep` and I just need simple changes to present it in the book. Well, it turned out lot more work and I had to settle for not covering all the options and customizations. In hindsight, would've been better if I did a separate book. Speed wise, `ripgrep` is very impressive when it comes to recursive searching and `gnu grep` is still faster for some cases when dealing with single large input file on my 5+ years old hardware. The multiline `-U` and replace `-r` options of `ripgrep` are quite handy - you can use this instead of `sed` for some cases with added advantage of speed, `-F` option and better regex features.

**Table of Contents**

* Preface
* Introduction
* Frequently used options
* BRE/ERE Regular Expressions
* Context matching
* Recursive search
* Miscellaneous options
* Perl Compatible Regular Expressions
* Gotchas and Tricks
* ripgrep
* Further Reading

Hope you find the book useful. I would be grateful for your feedback, book review and suggestions.

Happy learning :)

**PS** To celebrate the release, I'm also offering my e-book on **Python regular expressions** for half the price this week. Use these coupon links [gumroad](https://gumroad.com/l/py_regex/halfprice) or [leanpub](https://leanpub.com/py_regex/c/P7erPYAm1386) to get it.

After years of not having to touch office tools I tried to use LibreOffice writer. I'm sad to see it's light years behind its Microsoft counterpart.

Installing a language pack for spellchecking takes an awful lot of work. Truly sad to see.

There is a massive amount of work on Linux everyday and that's a great thing, but has the community lost its drive to make linux usable for the average (non-engineer) user?

Linux printing

I'm putting together a design document for printing on Linux but the only exposure I have are with consumer inkjet and laser models.

The print driver support seems to better with the enterprise multifunction devices, I've looked into the Canon models in the current environment as its a fair assumption that the new environment will probably end up with Canons as well and they are fully supported with deb and rpm drivers available.

What I need to know is if there are any printer manufacturers that are actively ignoring Linux these days or is support pretty good across the board?

kde transparency

iv tried the desktop effect called "translucency" but it only does so much. the "special application settings" seems perfect to set the transparency settings i want BUT only seems to effect one app. i really dont want to have to do them individually as this will take me hours just for the apps i have and then if i install new things later ill have to set it for them later. is there a way i can set this for all applications in one go and make it the default for everything so new apps will have it automatically set?
