Explain in detail the function of common catalogs in Linux

A commonly used first-level catalogue

Note:

1. Bin in the root directory and bin and sbin in the sbin,usr directory, all of which are used to store system commands.

2. Commands under the bin directory can be executed by any user, while commands under the sbin directory can only be executed by the super user.

3. Media is used to mount CD, misc to mount tape drive, and mnt to mount U disk. They are all empty directories.

4. Proc and sys directories cannot be operated directly. These two directories hold memory mount points.

5. You can put the content freely in the home directory root or home, as well as in the tmp directory.
