Write a script and run it via cron :).
Here's a sample that won't work, but it should give you the primary parts
you need.
###
#!/bin/path/to/bourne/derivative/shell
repos=/some/dir/
datum=`date +%Y%h%d`
# today's repos dir
trd=${repos}/${datum}
mkdir $trd
wget -O $trd/golden.$datum.html http://goldenhost/page.html
goldenhash=`md5sum $trd/golden.$datum.html | cut -d' ' -f1`
for i in `seq 1 50`; do
wget -O $trd/host${i}.$datum.html http://host${i}/page.html
iterhash=`md5sum $trd/host${i}.$datum.html | cut -d' ' -f1`
if [ $goldenhash != $iterhash ] ; then
borken="$borken $i"
fi
done
( for i in $borken; do
echo host${i}
diff $trd/golden.$datum.html $trd/host${i}.$datum.html
done ) | mail -s "Borken hosts $datum" $youraddy
###
That last piece doing the diff to mail probably formats horribly.
If you have questions about how parts of the code work please join the
devel list and ask there :).
There are definite improvements I'd make before putting code like this
live, but I think this takes care of your stated needs.
ciao,
