This article mainly introduces how to use the chcon command, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

The chcon command modifies the security context of the object (file), such as user, role, type, and security level. That is, change the security environment of each file to the specified environment.

Syntax chcon [options]... Environment files... chcon [options]... [- u user] [- r role] [- l range] [- t type] file. Chcon [options]. -- reference= reference file file. Option-h,-- no-dereference: files that affect symbolic links rather than references. -- reference= reference file: uses the security environment of the specified reference file instead of specifying a value. -R,-- recursive: recursively processes all files and subdirectories. -v,-- verbose: displays diagnostic information for all files processed. -u,-- user= user: sets the target security environment for the specified user. -r,-- role= role: sets the target security environment for the specified role. -t,-- type= type: sets the target security environment of the specified type. -l,-- range= range: sets the target security environment of the specified range.

The following options are used to set how to traverse the directory structure system when the-R option is specified

-H: if the command line argument is a symbolic link to the directory, traverse the symbolic link. -L: traverse every symbolic link to the directory that you encounter. -P: does not traverse any symbolic links (default). -- help: display this help and exit. -- version: displays version information and exits. Example
