Ten knowledge points that Linux beginners need to know

1.Linux is a case-sensitive system. For example, Mozilla, MOZILLA, mOzilla, and mozilla are four different commands (but only the fourth mozilla is really valid). Also, my_filE, my_file, and my_FILE are three different files. Users' logins and secrets are also case-sensitive (because the tradition of UNIX systems and the C language has always been case-sensitive).

two。 The file name can be up to 256 characters long and can contain numbers, periods, underscores, bars, and other characters that are not recommended.

3. The file name is preceded by "." Files are generally not displayed when entering the "ls" or "dir" commands. You can think of these files as implicit files, or you can use the command "ls-a" to display them.

4. "/" pair equals "\" under DOS (root directory, which means the parent directory of all other directories, or an interval symbol between directories and directories and files). For example, cd / usr/doc.

5. On Linux systems, all directories are displayed under a single directory tree (different from the drive ID of DOS systems). This means that all files and directories on all physical devices are merged under a single directory tree.

6. In the configuration file, the line that starts with # is the comment line. Try not to delete the old settings when modifying the configuration file-you can add "#" to the original settings into a comment line, and always add some comments about the changes accordingly. You will find that you will benefit a lot from future management.

7.Linux is an inherited multi-user operating system. Your personal settings (and those of other users) are placed in your home directory (usually / home/your_user_login_name). Many configuration files have the file name of "." At first, users generally do not see these files.

8. System-wide settings are generally placed under the directory / etc.

9. Like other multi-user operating systems, files and directories have their own owners and access rights under Linux. Generally speaking, you are only allowed to file to your home directory (/ home/your_user_login_name). Learn something about file rights management, otherwise you will definitely find Linux very troublesome.

10. Command parameter options are typically guided by "-" followed by a character (or "- -" when the option exceeds one character). In this way, "-" is a bit like "/" under DOS. For example, enter the command rm-- help.
