Examples
Change the owner user of a file/directory:
chown {{user}} {{path/to/file_or_directory}}
Change the owner user and group of a file/directory:
chown {{user}}:{{group}} {{path/to/file_or_directory}}
Change the owner user and group to both have the name user:
chown {{user}}: {{path/to/file_or_directory}}
Recursively change the owner of a directory and its contents:
chown {{[-R|--recursive]}} {{user}} {{path/to/directory}}
Change the owner of a symbolic link:
chown {{[-h|--no-dereference]}} {{user}} {{path/to/symlink}}
Change the owner of a file/directory to match a reference file:
chown --reference {{path/to/reference_file}} {{path/to/file_or_directory}}
