刚才在知乎什么看到了一篇分享pacbio的数据特征，顺便看到了Minnesota大学的关于生物信息的教程的ppt合集，所以就想打包下载。

https://www.msi.umn.edu/tutorial-materials

这个网页里面有64篇pdf格式的ppt，还有几个压缩包，本来是准备写爬虫来爬去的，但是后来想了想有点麻烦，而且还不一定会看，反正也是玩玩
就用linux的命令行简单实现了这个爬虫功能。
curl https://www.msi.umn.edu/tutorial-materials >tmp.txt
perl -alne '{/(https.*?pdf)/;print $1 if $1}' tmp.txt >pdf.address
perl -alne '{/(https.*?txt)/;print $1 if $1}' tmp.txt
perl -alne '{/(https.*?zip)/;print $1 if $1}' tmp.txt >zip.address
wget -i pdf.address
wget -i pdf.zip
这样就可以啦！
教程ppt列表如下，大家有兴趣的可以自行下载浏览。
