[建议]用别人的shell脚本时，还是现好好看看再说！！！

ychristian · #1

今天真郁闷，上网找了一个下载歌曲的shell脚本，先看了头几行，该了一下目录，然后运行，结果这个脚本把我的整个home目录中的用户目录都给删了。开始以为是别人搞的恶作剧，最后仔细看了看原来是自己修改的地方：

代码：全选

MP3URL="http://list.mp3.baidu.com/list/qingyinyue.html?top19"
WORKPATH="/usr/local"
HOMEPAGE="$WORKPATH/mp3/mp3.htm"

中间的

代码：全选

WORKPATH="/home/ycc"

然后在最后有一句。。。。。。

代码：全选

rm -rf $WORKPATH/mp3/tmp* [color=red]$WORKPATH[/color]  $WORKPATH/mp3/*.htm

竟然还是rm -rf

。。。这该让我怎么办阿。。。。。。。

特此说出来，大家以后要改别人的东西的时候一定要看完才好阿。

代码：全选

... 脚本本身没有这个的啊，莫非最后的

$WORKPATH /mp3/url*

之间有个空格?

这个.... 安慰下..

用自己写的才放心…

好可怜。。

这个空格怕是再小心也很难找的出来。。
