离网环境ubuntu安装依赖包是件很麻烦的事情，往往出现安装A需要依赖B，依赖B需要依赖C等等，下面脚本是递归下载用，用法是./XX.sh packname
#!/bin/bash
logfile=/root/log
ret=""
function getDepends()
{
echo "fileName is" $1>>$logfile
# use tr to del < >
ret=`apt-cache depends $1|grep Depends |cut -d: -f2 |tr -d "<>"`
echo $ret|tee -a $logfile
}
# 需要获取其所依赖包的包
libs="gnome-shell" # 或者用$1，从命令行输入库名字
# download libs dependen. deep in 3
i=0
while [ $i -lt 5 ] ;
do
let i++
echo $i
# download libs
newlist=" "
for j in $libs
do
added="$(getDepends $j)"
newlist="$newlist $added"
sudo apt download $added -d -y
done
libs=$newlist
done
