Linux Chown Command Examples to Change Owner and Group

The concept of owner and groups for files is fundamental to Linux. Every file is associated with an owner and a group. You can use chown and chgrp commands to change the owner or the group of a particular file or directory.

In this article, we will discuss the ‘chown’ command as it covers most part of the ‘chgrp’ command also.

1. Change the owner of a file
$ls -l filename
-rw-r--r-- 1 srinu chilukuri 0 2013-10-16 20:03 filename

$ chown root filename

$ls -l filename
-rw-r--r-- 1 root chilukuri 0 2013-10-16 20:05 filename

So we see that the owner of the file was changed from ‘srinu’ to ‘root’.
