Purpose:The stat command is used to display the status information of a file or file system, from the Coreutils software package, the general system comes with this command tool, which can obtain a lot of information related to the file system and files, the specific use of stat function options. This information includes Inode, Atime, CTime, Mtime, File (System) type, permissions, block size, symbolic connection, and so on.

syntax:stat [OPTION] ... FILE ..., can get its help information via stat--help or man stat

feature options: feature options need to be used in conjunction with the-c parameter, such as retrieving inode information for a file using stat, the inode number of the/filepath/filename file can be obtained with stat–c%i/filepath/filename.

For file systems:

Note: Using the-f option when the target file is the file system, such as retrieving the inode number of the file system with stat, uses Stat–f–c%c/filepath/filename to obtain the inode number of the/filepath/filename file system.

%Z Time of last change as seconds since Epoch The last change in the file (except the content also includes the permission information) time (Unix time)

Note: The content changes of the symbolic link file do not affect Mtime and CTime, only the target file.
