Get detailed status information for Linux file systems and files using the Stat command

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.

%a	Free blocks available to Non-superuser	Show remaining block information for non-superuser
%b	Total data blocks in file system	Total number of data blocks on file system

For files:

%a	Access Rights in octal	Octal File access rights

%g	Group ID of Owner	The group ID of the file owner
%G	Group Name of Owner	Group name of the file owner
%h	Number of hard links	Number of hard connections to a file
%i	Inode number	Inode number of the file
%n	File Name	File name
%N	Quoted file name with Dereference if symbolic links	If it is a symbolic link, the mapping relationship is displayed
%o	I/O block size	I/O block size
%s	Total size, in bytes	Total File Size
%t	Major device type in hex	Hexadecimal primary Device type
%T	Minor device type in hex	Hexadecimal secondary device type
%u	User ID of Owner	User ID of the file owner
%u	User Name of Owner	User name of the file owner
%x	Time of last access	Last access time of the file (Human readable)
%x	Time of last access as seconds since Epoch	Last access time of file (Unix time)
%y	Time of last modification	Time the last content of the file changed (Human readable)
%Y	Time of last modification as seconds since Epoch	File Last content Change time (Unix time)
%z	Time of last change	The last change in the file (in addition to the content also includes the permission information) time (human readable)
%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.
