Today, I would like to share with you how the Linux directory structure is related to knowledge, detailed content, clear logic, I believe that most people still know too much about this knowledge, so share this article for your reference, I hope you can learn something after reading this article, let's take a look at it.

When using Linux, you can see that there are many subdirectories (called first-level directories) under the Linux root directory (/) by typing ls-l / on the command line, such as bin, boot, dev, and so on. At the same time, each primary directory also contains many subdirectories (called secondary directories), such as / bin/bash, / bin/ed, and so on. The Linux file system directory is generally tree-shaped, and the / root directory is equivalent to the tree root.

[root@bogon /] # ls-l total 94 dr-xr-xr-x. 2 root root 4096 Aug 24 04:21 bin dr-xr-xrwx. 5 root root 1024 Nov 14 23:40 boot drwxr-xr-x. 2 root root 4096 Jul 14 2010 cgroup drwxr-xr-x. 17 root root 3760 Dec 19 18:25 dev drwxr-xr-x. 98 root root 4096 Dec 20 18:32 etc drwxr-xr-x. 12 root root 4096 Sep 29 00:29 home dr-xr-xr-x. 10 root root 4096 Aug 24 03:32 lib dr-xr-xr-x. 9 root root 12288 Aug 24 04:21 lib64 drwx-. 2 root root 16384 Aug 24 03:30 lost+found drwxr-xr-x. 2 root root 4096 Dec 4 2009 media drwxr-xr-x. 3 root root 4096 Aug 24 03:36 mnt drwxr-xr-x. 2 root root 4096 Aug 24 03:37 opt dr-xr-xr-x. 188 root root 0 Dec 12 21:56 proc dr-xr-x---. 25 root root 4096 Dec 5 00:19 root dr-xr-xr-x. 2 root root 12288 Aug 24 04:21 sbin drwxr-xr-x. 7 root root 0 Dec 12 21:56 selinux drwxr-xr-x. 3 root root 4096 Sep 29 00:30 srv drwxr-xr-x. 13 root root 0 Dec 12 21:56 sys drwxrwxrwt. 15 root root 4096 Dec 21 01:03 tmp drwxr-xr-x. 13 root root 4096 Aug 24 03:30 usr drwxr-xr-x. 22 root root 4096 Aug 24 03:33 var directory
