这是一个查看最新内核的小脚本
#! bin/bash
wget http://kernel.org/
n_line=0;
grep -A 1 stable index.html | while read LINE
do
n_line=$ ((n_line+1))
if [ $n_line = "2" ]
then

      LINE=${LINE#<*>}
      LINE=${LINE#<*>}
      LINE=${LINE%<*>}
            LINE=${LINE%<*>}
      echo "linuxzuixingneihe"
         echo $LINE
fi
done

exit 0

,可是运行后只是下载了网页,why?

你wget的就是网页，没文件啊！
wget http://kernel.org/
你这条命令意思就是下载http://kernel.org/，你应该是要下载一个文件，比如http://kernel.org/xxxxx.deb
