there's the need for me to have a CD (not DVD) with LMDE, because of non PAE CPU support. Since there's no CD image download anymore I tried myself with the help of this forum and several other sources to shrink the iso file.
At the moment I've no luck to get it shrinked to the estimated size inspite of purging more than 650MB from the linuxmint-201303-mate-dvd-32bit.iso.
After all processing I get about 1.04GB.
here is my script that does the work:
Code: Select all
#!/bin/bash
iso="linuxmint-201303-mate-dvd-32bit"
if [ "$UID" -ne "0" ]
then
echo "This script will only work when run by "root"."
exit 1
fi
# not everyone will have squash tools, install them if not found
if [ ! `which unsquashfs` ]
then
aptitude install squashfs-tools
fi
# not everyone will have genisoimage, install it if not found
if [ ! `which mkisofs` ]
then
aptitude install genisoimage
fi

END=$(date +%s)
echo "Done at `date`. The whole process took $(($END - $START)) seconds!"
Could anybody point me where to make efficient changes to the script, to get it done properly?
Thanks in advance!
kind regards
Christian
