This article is about the usefulness of the chgrp and chown commands in Linux. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Linux chgrp command

Function: change the group to which the file or directory belongs.

Syntax: chgrp [option] group filename?

This command changes the user group to which the specified file belongs. Where group can be the user group ID or the group name of the user group in the / etc/group file. The file name is a list of files to be changed to the group separated by spaces, and wildcards are supported. If the user is not the owner or superuser of the file, you cannot change the group of the file.

The options of this command mean:

-R recursively changes the grouping of the specified directory and all subdirectories and files under it.

Chown command

Function: change the owner and group of a file or directory. This command is also very common. For example, the root user copies one of his files to the user xu. In order to enable the user xu to access the file, the root user should set the owner of the file to xu, otherwise, the user xu cannot access the file.

Syntax: chown [options] user or group files

Description: chown changes the owner of the specified file to the specified user or group. The user can be a user name or user ID. A group can be a group name or a group ID. Files are a list of files to change permissions separated by spaces, and wildcards are supported.

The options for this command mean the following:

-R recursively changes the owner of the specified directory and all subdirectories and files under it.

-v shows the work done by the chown command.
