递归下载ubuntu下的某包安装包及依赖包

 1 #! /bin/bash
 2 basepath=$(cd `dirname $0`; pwd)
 3 pkg="$*"
 4 
 5 function getDepends()
 6 {
 7   ret=`apt-cache depends $1 |grep -i Depends |cut -d: -f2 |tr -d "<>"`
 8   if [[ -z $ret ]]; then
 9 #    echo '$1 No depends'
10     echo -n
11   else
12     for i in $ret
13     do
14        if [[ `echo $pkg |grep -e "$i "` ]]; then
15 #         echo "$i already in set"
16          echo -n
17        else
18          pkg="$pkg $i"
19          echo "Download $i ing"
20          getDepends $i
21        fi
22     done
23   fi
24 }
25 
26 for j in $@
27 do
28   getDepends $j
29 done
30 
31 echo $pkg
32 #apt install $pkg --reinstall -d -y
33 apt-get download $pkg -d -y

可以递归的把指定包及其依赖包下载回去安装， (.deb后缀)

有时候会出现安装失败的情况，这时应注意出错信息，去除该包后继续尝试下载，其实执行的命令如下

apt-get download python2.7 python2.7-minimal libc6 libgcc1 gcc-6-base libpython2.7-minimal zlib1g libpython2.7-stdlib mime-support libbz2-1.0 libdb5.3 libexpat1 libffi6 libncursesw5 libtinfo5 libreadline6 readline-common dpkg liblzma5 multiarch-support libselinux1 libpcre3 tar libacl1 libattr1 install-info libsqlite3-0 libssl1.0.0 debconf perl-base -d -y
