its pretty rough and incomplete but how about something like this:
#!/bin/bash
major_versions="2.1 2.9"
man="/usr/share/man/man1/"
bin="/usr/bin/"
for v in $major_versions
do
if [ $v == "2.1" ]; then VERSION=2.1.72; PRIORITY=80; fi
if [ $v == "2.9" ]; then VERSION=2.9.4; PRIORITY=70; fi
packages="octave$v octave$v-headers octave$v-emacsen octave$v-info"
for g in $packages
do
if [ -n `dpkg -l | grep -o "$g "` ]
then
case $g in
octave2.? ) OCTAVE="--install ${bin}octave octave \
${bin}octave-$VERSION $PRIORITY \
