Bash script to update WordPress

update_wordpress

#!/bin/bash

cd $1

if [ -f 'wp-config.php' ] && [ -d 'wp-admin' ] && [ 'wp-includes' ];
then
   rm -rf ./wp-admin
   rm -rf ./wp-includes
   cp -rf /var/www/wordpress/* .
   git add -u
   git commit -m "WordPress updates"
else
   pwd
   echo "This doesn't appear to be a valid WordPress instance"
fi

For safety, there are two requirements:

• must specify a directory (use . for current directory)
• must already be a valid WordPress instance

In addition, to reduce the presence of malware and other harmful code, please the note the wp-admin and wp-includes folder are completed removed and replaced.

Also, /var/www/wordpress should be a clone of WordPress on github ... use git checkout tag to ensure you're pulling the most updated version.

Finally, I recommend keeping each installation as a git repo so you can more easily track changes.
