Do not be afraid of Ubuntu command line

Article Title: Do not fear Ubuntu command line. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Command line is not a required skill to use Ubuntu. In general, the command line is required only when the first configuration and system problems occur after the system is installed. Like Windows, we almost do not need to use command lines in other daily operations, although Windows also has a DOS operation window.

However, it is easy to use the command line in Ubuntu. You only need to copy the command line on the web page and then open "Application-attachment-terminal ", click "edit-paste" in the terminal menu to paste the command line to the terminal window (Note whether a space is copied before and after the command line), and press enter to execute the command. Of course, you can also manually enter the command line in the book.

Some commands require you to enter the password and the password you used to log on to Ubuntu. The window does not display an asterisk like Windows (this is to prevent someone from remembering the length of your password ), it doesn't matter. after entering the password, press Enter.

As for the effects of command lines, if you are not interested in command lines, you can ignore them and continue using your mouse, you just need to learn to open the terminal and copy and paste the carriage return. (Again, remember to check whether there are any extra spaces after the command line is pasted. If so, delete the extra spaces and press Enter .)

PS: After you enter the password, the system will remember it within 15 minutes, so that you do not have to enter the password multiple times within 15 minutes.
