Shell脚本实现批量下载资源并保留原始路径

示例资源列表
如url.txt：

/file/imgs/upload/202206/04/cdtzdfhktoe.png

/file/imgs/upload/202206/04/t5utwv0rvyc.png

/file/imgs/upload/202206/04/0s1kgfk30zm.png

/file/imgs/upload/202206/04/jjzkcw2at41.png

/file/imgs/upload/202206/04/vjzxhnnwh3w.png

/file/imgs/upload/202206/04/g0awoqyllnq.png

脚本如下

如download.sh

#!/bin/bash

# desc: download resource

# author: 十年后的卢哥哥

mydir=`pwd`
while read line

do

{

    if [ -n "$line" ]

    then

        cd $mydir

        url=$(echo "$line" | tr -d 'r')

        picdir=$(echo $url | sed -r 's/Http:////g')

        picname=$(echo ${picdir##*/})

        picpath=$(echo ${picdir%}

${picdir%/*}

sh download.sh url.txt
