第一个脚本程序，自动生成离线升级包并自动删除旧包

[djhui]

此脚本须要有足够的硬盘空间，因为是第一个，所以可能不怎么好，请见谅

echo "Update the sources"
apt-get update
echo "Update the system & soft"
apt-get dist-upgrade -y

apt-get upgrade -y


if [ -e ~/edgy ]
then
echo ~/"edgy already existed"
else
mkdir ~/edgy
fi
echo "Copy files"
#cp -a /var/cache/apt/archives/* ~/edgy
cd ~/
echo "Make Packages.gz"
dpkg-scanpackages edgy /dev/null |gzip >edgy/Packages.gz

mkdir ~/temp_djhui_net
copy ~/edgy/Packages.gz ~/temp_djhui_net
cd ~/temp_djhui_net
gzip -d Packages.gz
cat Packages |grep ^Filename > temp
sed -e 's/Filename: /cp \~\//g' temp >temp1

sed -e 's/.deb/.deb \~\/new_djhui\//g' temp1 >temp2

mkdir ~/new_djhui

chmod +x temp2

./temp2

cp ~/edgy/Packages.gz ~/new_djhui

rm -rf ~/edgy
rm -rf ~/temp_djhui_net

mv ~/new_djhui ~/edgy
