Easily Change Ownership of File in Linux ▷ Chown Command

You'll eventually come across the need to change ownership of file or directory in Linux. The best method to do this is through the use of the chown command which stands for "Change Owner". This command allows you to easily modify the user and group ownership of a file or entire directory.

How the Chown Command Works

The basic syntax of the chown command to change the owner of a file or directory in Linux is as follows:

sudo chown [options] new_owner:group file_or_directory

Term	Description
`sudo`	Used to run the command with administrative privileges; changing owners often requires root or superuser permissions.
`new_owner`	Replace with the new owner's username or user ID.
`group`	Optionally set a new group name or group ID. If not specified, the file's group will remain unchanged.
`file_or_directory`	The path to the file or directory whose ownership you want to change.

How to Change ownership of file in Linux | Chown

Note that you will need appropriate superuser or root permissions to change the ownership of a file.

Open a Terminal. In Ubuntu or Debian, simply press Ctrl + Alt + T
Check the current ownership of the file (optional).
Before changing owners, you might want to verify the current owner. You can do this using the ls -l command. For example:
```
ls -l filename.txt
```
This will display information about the file, including the current owner and group.
Proceed to change ownership of a file using chown command.
For example, to change the ownership of filename.txt to user john, you would type the following:
```
sudo chown john filename.txt
```
