This article is about how to use the stat command in Linux system. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

In Linux systems, the stat command is mainly used to display the details of a file or file system.

Syntax stat [file or directory] parameter:-L,-- dereference: follow the symbolic link to parse the original file instead of the symbolic link;-f,-``file``-system: display the file system information instead of the file information;-c mathafe-``format`` = FORMAT: output in the specified format instead of the default format The format control characters available for ``display file information are as follows:``% a: display access rights in octal ``% A: display access permissions in readable form``% b: show the number of blocks occupied ``% B: display the number of bytes occupied by each block``% C:SELinux security context string ``% d: decimal display file device number``% D: hexadecimal display file device number ``% f: hexadecimal display file type``% F: file type. File types under Linux are mainly divided into ordinary files, directories, character device files, block device files, symbolic link files, sockets, etc. ``% g: file owner group ID``% G: file owner group name ``% h: number of file hard links``% i:inode number ``% m: mount point of disk partition where the file resides For example, ``/ data``% n: file name ``% N: file name enclosed in single quotation marks. If it is a soft link, the file name``% o:optimal I`` / O```file ``% s: actual file size is also displayed. Unit byte ``% t:major device ``type``in`` hex, ``for``in`` / block``device special files``% T:minor device ``type`in`` hex, ``for``sil`` / block``in``% u: owner user ID ``% U: owner user name``% w: file creation time, output-indicates that the file creation time is not known, output Unix timestamp 0 means you cannot know ``% x: output the last access time in readable form atime``% X:Unix timestamp output the last access time atime ``% y: output the last modification time mtime``% Y:Unix timestamp output mtime ``% z: output the last state change time ctime``% Z:Unix timestamp output final state change time ctime ``format controllers available for displaying file system information are:``% a: number of free block that can be used by non-super users ``% b: total number of block of file system``% c: total number of file nodes of file system ``% d: number of available file nodes``% f: number of available file block ``% I: hexadecimal file system ID``% l: maximum file name length ``% n: Name ``% s: size of a block Unit byte (``for```faster transfers) ``% S: basic size of a block, unit byte (used to count the number of block)``% t: hexadecimal output file system type ``% T: readable output file system type-``printf`` = FORMAT: output in the specified format instead of the default format. Similar to-- ``format``, but can interpret backslash escape characters, such as the newline character\ n;-t,-- terse: concise mode output, showing only summary information;-- help: displaying help information;-- version: displaying version information. Case demonstration: (1) display file information.

File: 'Changelog': file name is Changelog Size: 1598: file size 1598 bytes Blocks: 8: number of blocks occupied by the file IO Block: 4096: regular file: file type (normal file) Device: fd01h/64769d: device number of the file Display in hexadecimal and decimal respectively Inode: 1579435: file node number Links: 1: number of hard links Access: (0644 Maxima RW Murray r -): access rights Uid: owner ID and name Gid: owner user group ID and name Access: last access time Modify: last modified time Change: last state change time Birth -: cannot know the file creation time. Note: the file under Linux does not store the file creation time.

(2) display the information of the file system where the file resides.
