摘要:Shell脚本实现批量下载资源并保留原始路径
[b]示例资源列表
[/b]如url.txt:
[url=http://su.bdimg.com/static/superplus/img/logo_white_ee663702.png]http://su.bdimg.com/static/superplus/img/logo_white_ee663702.png[/url]
[url=http://su.bdimg.com/static/superplus/img/logo_white_ee663703.png]http://su.bdimg.com/static/superplus/img/logo_white_ee663703.png[/url]
[url=http://su.bdimg.com/static/superplus/img/logo_white_ee663701.png]http://su.bdimg.com/static/superplus/img/logo_white_ee663701.png[/url]
[url=http://su.bdimg.com/static/superplus/img/logo_white_ee663704.png]http://su.bdimg.com/static/superplus/img/logo_white_ee663704.png[/url]
[url=http://su.bdimg.com/static/superplus/img/logo_white_ee663705.png]http://su.bdimg.com/static/superplus/img/logo_white_ee663705.png[/url]

我们需要下载这些图片,并保存在各自的文件夹下。
[b]脚本如下[/b]
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
这里有几点要注意:
1、为了去掉文本文件中行末的换行符,要进行删除:
tr -d '\r'
2、取资源名:
${picdir##*/}
3、取资源路径:
${picdir%/*}
运行
sh download.sh url.txt
