I present to your attention the first (introductory) part of a series of posts devoted to working in the Linux command line. This post is a kind of foundation for future entries on this topic. It will be followed by posts with descriptions and practical examples of using popular console utilities.

I’ll give one recommendation right away. If you want a comprehensive resource on the Linux command line, I recommend reading William Shotts’ book with the simple title: The Linux Command Line. This book is an excellent source that lets you thoroughly study the basics of working in the Linux console. Material from this book will also be used and quoted in this and future posts about Linux.
