apt-get會下載deb包，但是不知道哪個先裝哪個後裝，用script記錄下載的順序。

之後可以不用上網，就把軟體程式安裝齊全

#!/bin/sh
echo "===" > res.txt
ls -l /var/cache/apt/archives/ > 1.txt
st1=`cat 1.txt | md5sum`
while [ 1 ]
do
    st2=`ls -l /var/cache/apt/archives/ | md5sum`
    if [ "$st1" != "$st2" ]
    then
        echo "change"
        ls -l /var/cache/apt/archives/ > 2.txt
        diff 2.txt 1.txt >> res.txt
        rm 1.txt
        mv 2.txt 1.txt
        echo $st1
        echo $st2
        st1=$st2
   
    fi
    sleep 0.1
done
