脚本 : DiskCheck
作者 : Nicky Wang
用途 : 检查磁盘空间使用情况
适用 : 文件服务器
功能 : 在config中设定允许的最大百分比,每天增长最大百分比,；如果有超出设定范围的，则会发mail通知相关人员。
前提 : 配置邮件服务器地址

这个脚本太过简单，谁都能看出来，呵呵，还需要做很多修改啊。

真他老老的狡猾的!哈哈!

谁写的啊?真聪明啊!

其实那段代码功能很弱，明眼人一看就知道有问题，根本不可能盗取什么密码。

我测试过了，明显和正常登陆的时候不一样。

[水成文]

那个盗取密码的脚本怎么回事？得在别人登陆的时候运行才有效啊。

感谢liquid_zigong兄

方法1：

#!/bin/sh

TEMP=.tmp

for file in *.mpc
do
        mppdec "$file" $TEMP && lame --preset extreme $TEMP "${file%%.mpc}.mp3"
        rm -f $TEMP
done

方法2: (用命名管道)

#!/bin/sh
FIFO=/tmp/$$.wav

mkfifo $FIFO         #不是wav文件mppdec拒绝输出
for file in *.mpc
do
         mppdec "$file"  "$FIFO" &
         lame --preset extreme "$FIFO" "${file%%.mpc}.mp3"
         echo "$file" is done
done
rm -f $FIFO

liquid_zigong兄解说：
mppdec可是大名鼎鼎的MusePack(mpc)音频格式的Linux版播放器。它也可以用来把MPC文件转化成WAV。不过它似乎不能把输出重定向到标准输出，所以得用命令管道才能实现即时(on-the-fly)编码。而且输出名字必须有.wav后缀，不然有问题

MPC的音质和效率可比MP3高多了，它有XMMS的plugin,可自行安装。
它的编码器叫mppenc

这些脚本很好，可以我在公司不能天天上网，只能传文件。
要是有那位大虾把这些脚步都打包，就好了。
