Directory composition structure in Linux system

The directory composition class of the Linux system is like an inverted tree structure, which begins to extend downward with a directory called root ("/").

It is different from other operating systems. Windows, for example, in windows, there are as many roots as there are partitions, and these roots are juxtaposed, while in Linux, no matter how many partitions there are, there is a root.

The corresponding folder type character in the Linux system is "d"

The current path is / tmp/1/2/3/4, then cd.. /.. It's just the / tmp folder.

Directory access permission

A directory is a special file.

The read and write execution permissions on the directory are different from those of ordinary files

Read: users can read the files in the directory, that is, decide whether they can type ls in this folder.

Write: it doesn't work if you use it alone. It is used in conjunction with read and execute permissions to add and delete files in a directory

Execution: users can enter the directory and call the data in the directory. All users must have execution permission to cd into this folder.
