This article mainly introduces the method of linux to view the file format, which has a certain reference value, friends who need can refer to it. I hope you will learn a lot after reading this article. Next, let the editor take you to learn about it.

Common Linux file types are: ordinary files, directories, character device files, block device files, symbolic link files and so on.

Linux's way to view the file format:

1. Ls-l or ll (ls-l alias)

# ll anaconda-ks.cfg / / look at the first character-rw-. 1 root root 2460 June 1 23:37 anaconda-ks.cfg

2. File command

[root@xiaochen ~] # file anaconda-ks.cfg anaconda-ks.cfg: ASCII English text

3. Stat command

# stat install.log / / View the detailed attributes of the file (including the file time attribute) File: "install.log" Size: 34793 Blocks: 80 IO Block: 4096 General file Device: 802h/2050d Inode: 65282 Links: 1Access: (0644mow Uid: (0 / root) Gid: ( 0 / root) Access: 2017-06-05 16purl 53 purl 20.000000000 + 0800Modify: 2017-04-22 1349purl 46.0000000000000 + 0800Change: 2017-04-2213lv 49purl 52.000000000000 + 0800

Linux file type:

1. Common file types

One of the most common file types in Linux, including plain text files (ASCII), binary files (binary), data format files (data), and various compressed files. The first attribute is [-].

2. Directory file

This is the directory, which can be accessed with the # cd command. The first attribute is [d], for example, [drwxrwxrwx].

3. Character device or block device file

Block device file: an interface device that stores data for system access, simply a hard disk. For example, the code of hard disk No.1 is / dev/hda1 and other files. The first attribute is [b].

Character device file: the interface device of the serial port, such as keyboard, mouse, etc. The first attribute is [c].

4. Socket file

Such files are usually used for network data connections. You can start a program to listen to the client's requirements, and the client can communicate through sockets. The first attribute is [s], which is most commonly seen in the / var/run directory.

5. Pipeline file

FIFO is also a special file type, and its main purpose is to solve errors caused by multiple programs accessing a file at the same time. FIFO is the abbreviation of first-in-first-out (first in first out). The first attribute is [p].

6. Link the file

Similar to the shortcut below Windows. The first attribute is [l], for example, [lrwxrwxrwx].
