But who are we?

Petru: the infamous coder with many years of Linux experience. He types like crazy, loves doughnuts and has Linux wired in his brain! After discovering Linux and switching through a different distribution every week, annoying his girlfriend with tons of geeky stuff, now he annoys everybody with geek talks and the latest news in the tech world.

He spends his time coding frontends, backends, databases, Linux servers, and clouds.

Bogdan: the deserter! He went through more than 20 Linux and Unix distributions including Plan 9, HP-UX and all of the BSDs. But after his girlfriend left him because he spent way too much time in front of the computer he… switched to Mac.

Now he spends his time teaching over ten thousand students in his 8 online courses.

And we are here to help you double your terminal productivity!

If you don't know how to use sed, if you're not that used to pipeing commands, if you use the default terminal and if you are still using BASH then this book is for you.

Read it now and double your terminal productivity!
