Presupunem ca ati ales aceasta carte pentru ca aveti nevoie deja sau va intereseaza sa invatati sa utilizati Unix sau orice sistem de operare asemanator cu Unix, cum ar fi Linux, Mac OS X, BSD, HP UX, AIX, Solaris sau altele. Presupunem ca Doriti sa stiti sa utilizati Unix pentru a lucra cu el la birou, la scoala sau acasa. Poate ati mai lucrat cu Unix, sau poate nu. Nu este neaparat necesar sa aveti cunostinte sau aptitudini neobisnuite de lucru cu calculatorul. Doriti sa invatati Unix, dar probabil nu doriti sa fiti coplesit de toate detaliile incalcite referitoare la sistemul Unix. Pe scurt, pornim de la presupunerea ca doriti sa utilizati Unix pentru a va atinge scopurile legate de utilizarea calculatorului. Doriti sa stiti ce puteti face, doriti sa va formati o idee in privinta potentialului unei comenzi si sa invatati sa lucrati inteligent. Foarte intelept. Puteti face toate acestea folosind cartea de fata. In esenta, tot ce va trebuie este sa accedeti la un sistem sau cont Unix si sa aveti un scop (sau mai multe) pe care doriti sa‑l atingeti.
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.
