We sometimes forget that those shiny graphical apps like firefox can be controlled from the commandline, too!

For example, here's a way to automatically open up all articles that are currently on this site's main page, each one in its own tab:

#!/bin/sh

TMPFILE=`mktemp`
URL="http://www.debian-administration.org";

wget -q $URL -O - | sed -n "s#.*<h2 class=\"title\"><a href=\"\(\/articles.*\)\".*#$URL\1#p" > $TMPFILE

I=0

while read line
do
  firefox -new-tab $line &
  if [ $I -eq 0 ]; then
     sleep 5
     let "I+=1"
  fi
done < $TMPFILE

rm -f $TMPFILE

( after opening up the first article we better sleep for 5 seconds, otherwise we end up with many firefoxes)
