如url.txt:

我們需要下載這些圖片,并保存在各自的文件夾下。
腳本如下如download.sh
#!/bin/bash# desc: download resource# author: 十年后的盧哥哥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這里有幾點(diǎn)要注意:
1、為了去掉文本文件中行末的換行符,要進(jìn)行刪除:
tr -d '/r'
2、取資源名:
${picdir##*/}3、取資源路徑:
${picdir%/*}運(yùn)行sh download.sh url.txt
