### upgrade-wp - updates installed WP sites from list to new version 
###  Originally it just: cd $DOMAIN; copy in new files, chown them over, click links.
###  Now variablized to support most setups, but public_html style additional
###  folders in the path would require more complex logic.

### Edit these for the server before running
web_user=christal
web_home=/web/sites/
## Desired version of WP
target_version="2.5.1"
## list of wordpress domains, one per line
wp_sites=wp_sites
## this is actually just tilde on a standard install:
tilde=/web/sites/sysadmin

###check for the input file and die if not found
if ! [ -x "$wp_sites" ]
  then echo "uwp: WP sites file $wp_sites not found. nothing to do." && exit ## syntax for -1 ?
fi

###check to see if we have the wp files local already, and if not, grab them
### and put them in a specific place. Logic: If the file exists in the
### wpu directory, we've run before here and can proceed, else, set it all up.
### If this is somehow a concern you could add a cookie string to wpu and
### match for that.

## check ~/uwp for wordpress-$target_version.tar.gz
## if not, make the folder, get it and untar it
if ! [ -x "$tilde/wpu/wordpress-$target_version.tar.gz" ] 
  then
    mkdir $tilde/uwp/; cd $tilde/uwp
    ## wget -q ?
    wget -q http://wordpress.org/latest.tar.gz
    tar zxf wordpress-$target_version.tar.gz || echo "uwp: Untar failed!" && exit 
fi


### the main upgrade loop
for domain in `cat wp-sites` 
do
  #
  echo -n "uwp: $domain upgrading ... "
  cd $web_home/$web_user/$domain
  cp -r $tilde/uwp/wordpress/* .
  chown -R $web_user:www-data *

  # have WP do all the work for us, thanks! curl -q is quiet?
  curl -q http://www.$domain/wp-admin/ > /dev/null
  curl -q http://www.$domain/wp-admin/upgrade.php?step=1&backto=%2Fwp-admin%2F > /dev/null

  echo "$domain upgraded."
