SEE: the comment by OGC Member. He explains how to modify the code in the footer.php file located in the Themes – Twenty Thirteen directory. Only the second line of his example code needs to be inserted and customized. Remember to backup the original footer.php file before you make your edits. I recommend that you install and use the app ‘Notepad++’ as your php files editor. Windows notepad is rather inadequate.
Example: You can add your owe copyright notice to replace the phrase Proudly Powered by WordPress.
Login to remote Ubuntu install through App ‘Putty’ using ssh using and login with the ‘root’ administrative user.
You can copy the content of a folder /source to another existing folder /dest with the command
cp -a /source/. /dest/
The -a option is an improved recursive option, that preserve all file attributes, and also preserve symlinks.

If you first need to make a new target directory/folder, then you can use the mkdir command, like this:
All this is useful if you want to re-install a MySQL server that won’t start, and making backups lessen the risk of loss of database files.
MySQL database files are stored in /var/lib/mysql. This folder ‘should’ remain untouched when you remove or re-install the MySQL package.
It is also a good idea to make a backup of those database files. I did so using the copy command above.
