We have an issue where our developers try to update the core WordPress files. I wanted to find a way to keep them honest. here is my script:

# get WordPress
cd ~/src/
rm -f ~/src/latest.tar.gz
rm -rf ~/src/wordpress/
wget -q http://wordpress.org/latest.tar.gz
tar -xzf latest.tar.gz
CURRENTVERSION=$(grep "wp_version =" ~/src/wordpress/wp-includes/version.php | cut -f 3 -d " " | sed "s/;//" | sed "s/'//g")
# find WordPress installs and compare
for installpath in $(find $SEARCHPATH -name wp-config.php)
	do
		BASEDIR=$(dirname $installpath)
		INSTALLEDVERSION=$(grep "wp_version =" $BASEDIR/wp-includes/version.php | cut -f 3 -d " " | sed "s/;//" | sed "s/'//g")
		if [ $CURRENTVERSION == $INSTALLEDVERSION ]; then
		echo "====Comparing $BASEDIR to Source====" 
		diff -rq --exclude="wp-content" ~/src/wordpress  $BASEDIR #| grep differ
		fi
done

Below is my current WordPress update script. First this script downloads the most recent version and determines which version it is:

cd ~/src/
rm -f ~/src/latest.tar.gz
rm -rf ~/src/wordpress/
wget -q http://wordpress.org/latest.tar.gz
tar -xzf latest.tar.gz
CURRENTVERSION=$(grep "wp_version =" wordpress/wp-includes/version.php | cut -f 3 -d " " | sed "s/;//" | sed "s/'//g")
echo "Latest Version: $CURRENTVERSION"

Next it looks for all wp-config.php files in all the websites to identify which sites have WordPress installed. Then and finds the version from the versions.php script. If the version is not equal to the most recent downloaded version (from the code above), it copies the updated source to the website:

for installpath in $(find /webdir -name wp-config.php)
	do
	BASEDIR=$(dirname $installpath)
	INSTALLEDVERSION=$(grep "wp_version =" $BASEDIR/wp-includes/version.php | cut -f 3 -d " " | sed "s/;//" | sed "s/'//g")
	if [ ! $CURRENTVERSION == $INSTALLEDVERSION ]; then
		echo "updating" $BASEDIR from $INSTALLEDVERSION "to" $CURRENTVERSION
		cp -R  ~/src/wordpress/* $BASEDIR/
	else
		echo $BASEDIR "is already" $CURRENTVERSION
	fi
	done
