如url.txt:
http://su.bdimg.com/static/superplus/img/logo_white_ee663702.pnghttp://su.bdimg.com/static/superplus/img/logo_white_ee663703.pnghttp://su.bdimg.com/static/superplus/img/logo_white_ee663701.pnghttp://su.bdimg.com/static/superplus/img/logo_white_ee663704.pnghttp://su.bdimg.com/static/superplus/img/logo_white_ee663705.pnghttp://su.bdimg.com/static/superplus/img/logo_white_ee663706.png
我们需要下载这些图片,并保存在各自的文件夹下。
脚本如下如download.sh
#!/bin/bash# desc: download resource# author: 十年后的卢哥哥mydir=`pwd`while read linedo{ 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 < $1exit 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
