Summary of problems often encountered when using Linux for the first time

Users who are accustomed to using Windows systems are inevitably somewhat uncomfortable when using Linux systems. The following small series gives you a list of common problems and solutions when using Linux systems. Let's learn together.

Q: Why can not our terminal password?

A: In fact, the terminal does not have the possibility to enter a password, because the user's password is very important in the Linux system, so entering the password in the terminal and other programs will not echo any symbols, such a design In order to avoid others remembering your password digits and crack your password, so when you enter the password in the terminal, please blindly type the password and tap Enter!

Q: Where is my C drive?

A: The file system structure under Linux system is completely different from Windows. If you really want to say C disk under Linux, then you can only say /, if you say Linux user folder, it is /home For a more detailed explanation, you can check out Deepin Encyclopedia. In addition, imagine the file system structure of Linux system as a big tree, which can quickly help you understand the file system structure under Linux system.

Q: Where is my software installed?

A: This problem is related to the above problem, although the Linux system C:\\Program Files is /usr, but not all software installed files are under /usr, software under Linux system Files are generally scattered under multiple directories under Linux.

Q: What are the best optimization and cleanup software under Linux?

A: Because the Linux system is inherently good design, no optimization software is needed. If you really need "optimization", then you can try the following work:

Optimizing the Linux kernel Configuration, streamlining the functionality and size of the kernel

Turning off some services that are not needed or not commonly used

But in the current situation where the computer has a lot of performance, the above work does not significantly indicate the Linux system. Performance, on the contrary, will turn off some of the available features. As for the cleaning system, there is no junk file under the Linux system. Generally, only the cache file is stored in the /tmp directory, and the directory is automatically cleaned up periodically, without the user having to worry about it.

Q: What are the useful anti-virus software under Linux?

A: Because of the strict permission mechanism under Linux system, there are few threatening viruses under Linux system, and Linux can't run the virus under windows system, so Linux system is inherently safe, but you should pay attention to it. Don't let your root password and personal user password leak, and don't run scripts that don't know the source and function. You can do this without worrying about Linux system security.

Q: Where do I go to download and install the software?

A: The depth store is born for this. You only need to open the depth store to use the mouse to install any software you like. As for the online installation and installation and PPA installation, I It is recommended that you first have a certain understanding of the system's package manager tool before you try.

Q: How do I distinguish between system updates and software updates?

A: Because the Linux system is a system with very tight systems and software, it is difficult to distinguish between system and software updates. My suggestion is to update the system when prompted.

Q: Why can't I install multiple software at the same time?

A: This problem involves software dependencies under the Linux system, so Linux system installation software can not be installed in parallel.

The above is the introduction of Linux problems and solutions. If you have not used Linux system, or just touched Linux system, the content of this article may be understood.
