Static Blogrolling

In the interest of more accessible and indexable Blogrolling, I use a combination of PHP, cron, and some scripting to avoid the more commonly seen JavaScript route. I thought I'd share with the Googlebot, who seems to be my most frequent visitor, second only to myself.

Here's the script:

#!/bin/sh

WEBDIR=/var/www/blogs.bwerp.net/htdocs
URL="http://rpc.blogrolling.com/display_raw.php"
ROLLID="r=11a89b51a86123178572ef64d4d87f02"

/usr/bin/curl "${URL}?${ROLLID}" -s -o ${WEBDIR}/blogroll.html.new

if [ $? -eq 0 ]; then
    mv ${WEBDIR}/blogroll.html.new ${WEBDIR}/blogroll.html
else
    echo "blogroll.sh failed: $?" 1>&2
fi

Cron runs this every fifteen minutes, so my blogroll is pretty up-to-date. Note that I don't replace blogroll.html right away. If curl can't run for whatever reason (or if the network is slow), it's going to create a text file that's blank, which is a Bad Thing. So, I create a temp file, and if all went well, I rename it so it becomes the include.
