được dựa trên trình duyệt web được cài đặt trên hệ thống. Trong trường hợp này, chúng ta hãy nói rằng Konqueror là trình duyệt web của chúng tôi. Để sử dụng Konqueror để điều hướng các hệ thống tập tin, chỉ cần mở trình duyệt và sử dụng các lĩnh vực vị trí để xác định đường dẫn của bạn chính xác như bạn sẽ chỉ định nó ở dòng lệnh Unix. | 70 anything. You should view the original source filename and make sure that when you build a link that you specify the exact filename to avoid this error. Another issue you may face involves forgetting to use the -s option. The -s option is nothing more than specifying that you want to create a soft link instead of a hard link. Since hard links are not really used by Unix end users we will not dig too deeply into the meanings here as it s a bit beyond the scope of this book and not likely to be anything you will see or use as a novice user of Unix. As I mentioned earlier in this book it s imperative that you take the initiative to dig into these topics deeper on your own if you are interested in all that you can do with Unixkeep learning and practicing as much as you possibly can. An example of the In command to create a link can be seen here ln -s priv home rob storage HTML etc HTMLLAB easy If you were to do this you would create a link named easy in the HTMLLAB directory that would be linked to the very long and not easy to remember HTML file located in your stored HTML directory. That s it That s creating a link and now you not only know how to do it but a practical reason why you should. Our last discussion in this lesson focuses on the proper way of using relative or absolute paths. Knowing the Right Path We discussed the difference between relative and absolute paths in Lesson 5. By managing data using commands such as cp and mv you can also specify different paths when issuing the command. There are shortcuts and other tips that could fill 50 of these books that can help you be more productive. It is very important to remember that when you give a filename as an argument to a Unix command the filename can be either a relative or absolute path to the file. Consider this when you type out your command. Sometimes you may not be specifying the command properly and that is why it s failing for example if relative and absolute paths either use or
