Covers the basic concepts of the computer operating system and discusses topics such as using directories, working with a shell, configuring the Unix environment, writing scripts, and working with encoded files.
A quick course on Unix. Very clear, straight to the point with examples and screen shots.
The book focused on the usage of basic Unix commands in dealing with directories, files, accounts, some system configurations and emails. For each command, the book provided with a brief explanation of its functionality, a couple of -flag options and some demonstrating examples (with screen shots which I found very helpful). Upon finishing the book (and preferably working out the examples), the reader should be comfortable with the Unix terminal.
Note that the book didn't explain the principles of Unix system or how to get one. It assumed you have a machine running Unix and someone (system administrator) configured it for you. All you need to do is to learn how to use it, by the terminal. It seems that is no longer the case in these days where most of the personal computers have GUI. Given, for those who want to learn the basics, this is an easy start.
I should also make clear that: - The book was published in 1998. However, all the basics of Unix have essentially remained the same since then. So most, if not all, information presented in the book are still valid. - I tried to learn how to use Linux, not Unix. Some commands in the book do not work on my Linux machine (but most do!). I skipped some parts on text editing and emails that seem to be out-dated in this era of GUI.
I loved this book because it contains clear explanations about the most used commands in the Unix/Linux world. The author makes a great job by providing examples, along with screenshots of the text editor windows and shell outputs.
