Changing file or directory ownership

Use the chown command to change the owner of your files.

When you specify the -R option, the chown command recursively descends through the directory structure from the specified directory. When symbolic links are encountered, the ownership of the file or directory pointed to by the link is changed; the ownership of the symbolic link is not changed.
Note: Only the root user can change the owner of another file. Errors are not displayed when the -f option is specified.
For example, to change the owner of the program.c file, type the following:
chown jim program.c

The user-access permissions for the program.c file now apply to jim. As the owner, jim can use the chmod command to permit or deny other users access to the program.c file.

See the chown command for the complete syntax.
