Like every traditional UNIX system, Linux also uses the system root filesystem: it is directly installed by the kernel in the boot phase, it also has the system initialization script and the most basic system program.   Other file systems are either

  Introduction In the previous content, we mentioned that the traditional permission has only three identities (owner, group, others) combined with three permissions (r, w, x) and three special permissions (SUID, SGID, SBIT), with the development of

The existing directory is shared between virtual machines and Linux, but each time the program calls the newly created file, it finds no permissions.This specifies that a new file or directory under a specific directory and its subdirectories has

The existing Directory is shared by virtual machines and Linux, but no permission is found for each file created by calling a program. Therefore, specifying the file or directory created in a specific directory and its sub-Directories gives the user
