Detailed explanation of Linux The role of commonly used directories
A commonly used first-level directory
Note:
1. Bin and sbin in the root directory, and bin and sbin in the usr directory. These four directories are used to save system commands.
2. Any user can execute the commands in the bin directory, and only the super user can execute the commands in the sbin directory.
3. media is used to mount the CD, misc is used to mount the tape drive, and mnt is used to mount the U disk. They are all empty directories.
4. The proc and sys directories cannot be directly operated. These two directories store memory mount points.
5. You can place any content in the root or home directory, as well as the tmp directory.
