2004.8.3 Tuesday
The UNIX tutorial is a total of fourteen, yesterday, four pages, today's fourth page, the progress arrangement every day is very average.
Yesterday, I introduced Unix history, origin, species, and version. Named SUN OS, Salaris, IBM AI, and HP. We introduce and explain the OS 5.8 launched in Sun 2000.
Today introduced the command. Ls lists files and directories; CD changes path; MKDIR builds a directory; Touch creates file or modify the file access time; chmod changes file directory properties; CP
Copy; MV move; ID, WHO am i, and WHOAMI all show own residences; Man find help information. A big piece of content today is the introduction of VI, this Unix function is
Notepad is far from the same editor. Edit, command, and final row mode (three modes are switched through the ESC key), let us be helpless, bored on the head! Half-talence
The mouse has fallen early. Could it be ... After his head is hurt, he is a happiness: this is a bit of high-tech taste. Don't understand the little fart in Windows seven or older, you can do it before the mouse can be done before the computer.
There is a model. It does not reflect the mystery of the computer. :) Teacher Zhao talked about it after a while, let us practice, practice VI this will consider lunch time. Teacher Zhao placed the next question, who first done to eat first. The voice just fell, a good guy, he only heard the keyboard ring.
Sound. Everyone rigs and races in the belly!
The use of orders is more intuitive, miscommines, and there is no logical connection between commands. That, huh, let's practice! Traine the get out of class, practice, practice at night, keyboard sound!
2004.8.4 Wednesday
On the last day of UNIX learning, today's content can be divided into three pieces: network part, setting environmental files, and how to control (SLEEP, KILL).
The network part initially introduces the theoretical knowledge, LAN, WAN, Subnet Mask, TCP / IP ..., then the specific command: telnet (login connection remote host), Mailx (sending and receiving mail), Talk (talk to someone), Wall Send information to all users). The most interesting is FTP, PUT uploads local files, GET downloads from the server. After the Norton firewall is installed, the students cannot share access from each other. This is much better after I have FTP. Note that when using ftp, it is an ASI or BIN mode, otherwise the shared file will appear. In addition, FTP does not support the entire directory to download, don't tighten, can be packaged! Taking the non-slaughter belly skin that I can't use the boat, this is one of the goals of UNIX: backup every day of work content (implementation via FTP).
Unix is a multi-process, multi-user, multi-task operating system, what should I do if I do? You can use PS, Jobs to review (this reminds me of the Win2000 to press CTRL Alt DEL to appear on the task manager), and then subjected to Sleep or Kill a process.
Teacher Zhao said that he often tested another PATH when he was recruited. Many Unix masters often spend our question. This can be paid attention to. HOME DIRECTORY has a .Profile file saves some settings for the system. For a login to take effect, we can also change through Export, but this modification in the command line only affects the current session, next time login and invalid. To change permanently, you can use VI to change the contents of the.profile file. The class is over three pm, and the time is practiced. Take careful weight, today's content is the most cost-robin these days. And .Profile settings are directly related to Oracle. Learn so many orders, how to use in actual work? In the next 5 days of Oracle learning, you can see it.
