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：

http://su.bdimg.com/static/superplus/img/logo_white_ee663702.png

http://su.bdimg.com/static/superplus/img/logo_white_ee663703.png

http://su.bdimg.com/static/superplus/img/logo_white_ee663701.png

http://su.bdimg.com/static/superplus/img/logo_white_ee663704.png

http://su.bdimg.com/static/superplus/img/logo_white_ee663705.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%/*})

        mkdir -p $picpath

        cd $picpath

        wget -O $picname `echo $url`

    fi

}

done < $1

exit 0

1、为了去掉文本文件中行末的换行符，要进行删除：

tr -d 'r'

${picdir##*/}

${picdir%/*}
