Reassigning the Owner
The chown command (CHange OWNer) is used to change the user who owns a file or directory. This command generally requires sudo privileges, as normal users cannot give away files they own.
Syntax
chown [options] new_owner file/directory
Changing User Ownership Only
To change the owner of website_data to a user named www-data:
bash $ sudo chown www-data website_data
Changing Both User and Group Ownership
Use a colon (:) to separate the user and the group.
To change the owner to admin and the group to devs:
bash $ sudo chown admin:devs project_files
Changing Ownership Recursively (-R)
To change the ownership of a directory and all its contents:
bash $ sudo chown -R admin:devs project_files
