Βασικές εντολές Linux σε Backtrack 5 R3

Για τους αρχάριους χρήστες των συστημάτων UNIX LINUX σε αυτό το tutorial παρέχεται μια λίστα με τις βασικότερες από τις εντολές τερματικού σε περιβάλλον Backtrack 5 R3. Μπορεί σε μερικούς η χρήση λειτουργικών συστηματων UNIX να φαίνεται λίγο δύσκολη αλλά δεν είναι. Με τη χρήση τέτοιων λειτουργικών συστημάτων και κυρίως των Linux είναι μια πολύ καλή ευκαιρία για πολλούς να μπουν στον κόσμο των Linux και να αποκτείσουν γνώσεις πάνω σε υπολογιστές περισσότερες απ' όσες μπορεί να παρέχονται από άλλα λειτουργικά συστήματα. Να επισημάνουμε ότι η γνώση παρέχεται δωρεάν και ειδικά σε περιβάλλοντα Linux που δε χρειάζεται κανένα κόστος για να εγκαταστήσει κανείς τα Linux, μιας και αποτελεί λειτουργικό σύστημα ανοιχτού κώδικα, δηλαδή παρέχεται δωρεάν από την ημερομηνία δημιουργία τους.
