WordPress Update Bash Script

I wrote this script some time ago. It's been working flawlessly for me, so I thought I'd share it here. It could use some progress messages, I suppose.


#!/bin/bash
DIR= # Put the file system path to your WordPress installation here. E.g., /var/www/html/blog
TMPDIR=$HOME/tmp
WPDIR=$TMPDIR/wordpress
cd $TMPDIR
rm -rf latest.zip ./wordpress # Clean up from the last run
wget -nd http://wordpress.org/latest.zip
unzip latest.zip
mv $DIR/wp-config.php $DIR/.config # Stash your configuration someplace safe
rm $DIR/*.{txt,html,php} # Delete the old install
rm -rf $DIR/{wp-admin,wp-includes} # Delete more. Don't delete plugins or themes.
cp -aR $WPDIR/* $DIR/
mv $DIR/.config $DIR/wp-config.php # Restore the configuration
# You may not need the last two lines. I like to give my web server the ability to write files.
chown -R .www-data $DIR/*.php $DIR/wp-admin $DIR/wp-includes
chmod -R g+w $DIR/*.php $DIR/wp-includes
