(e.g. Vamei) and password, done!In the following procedure, you will operate the computer as a user Vamei. In addition, depending on your settings when you create a user, Linux will also put you in a group, such as a stupid group, or a Vamei group.So you will be a user Vamei and a member of the Vamei group. (Note that group Vamei and user Vamei only have the same name, so you can call Dell, as well as Dell's boss.) You can also be a user Vamei, as we

Management Memory management Provide file functionality Provides network functionality Provides hardware drivers Provide security mechanismsThird, the Shell interface of LinuxThe Linux user interface is divided into a graphical interface and a command line interface.Shell of the command line:ShBashCshKshZshTcshThe default shell is bash,

, then alias execution will directly find the specific file and skip all subsequent searches (that is, keyword->function,-> Built-in-> $PATH). Please keep an eye out for them.Finally, when you do the experimental verification can be divided into 2 types of verification, because a command cannot belong to both keyword and built-in, so you can:　　1) Select a keyword such as while, define a while alias,function, and then write a shell script name for while stored in the path variable at a certain pa

In fact, no matter what system you learn, it is very important to start from scratch! What do you do when you get started with Microsoft Windows? It's not just the case that the archive manager learns, and then slowly plays to the console, plays to desktop management, and then learns office software. I think, shouldn't you skip this learning course directly? SoLinuxIn fact, the learning is similar, that is, to learn from the beginning slowly! I want to learn to fly before I can't walk! ^_^! Some

You can install Ubuntu tweak by searching for Ubuntu-tweak in the Ubuntu Software Center. After installing Ubuntu Tweak, we can also add the PPA of the direct-to-use software via the Software Source Center in Ubuntu Tweak, adding a process more convenient.Now we understand some of the basics that are needed to
