昨天在机房等待复制数据(332G)时，实在等待的无聊，就写了这么个东西；主要用于当开始一个复制操作时，如果量比较大，我们又必须等待其完成，每次通过du查看的数据，自己要算一下才知道大概有多久；这个很麻烦，于是想，这应该是个很简单的脚本；
先说操作前提，首先得有正在复制的东东，文件或目录皆可，然后要给脚本一个间隔时间，脚本通过间隔时间来计算平均每秒复制速度，然后还要告诉脚本源文件和目标文件，当然目录也可以。
如下：
./script.sh 10 /nfs/openSUSE-11.2-DVD-x86_64.iso /opt/os/openSUSE-11.2-DVD-x86_64.iso Speed: 13.20MB/s; Done: 0.12GB; 121.00MB # 每秒平均速度，完成的GB多少，MB多少 Time: 5.45 sec; Have: 4.22GB; 4316.41MB # 预计还需要多少分钟，还有多少没复制，其大小是多少GB，MB 代码如下：
123
./script.sh10/nfs/openSUSE-11.2-DVD-x86_64.iso/opt/os/openSUSE-11.2-DVD-x86_64.isoSpeed:13.20MB/s;Done:0.12GB;121.00MB#每秒平均速度，完成的GB多少，MB多少Time:5.45sec;Have:4.22GB;4316.41MB#预计还需要多少分钟，还有多少没复制，其大小是多少GB，MB
