做DD迁移时候的监控脚本，很有用的哟

在通过dd实施存储迁移，或者别的裸设备数据迁移时，一般通过后台脚本执行，下面脚本就是监控dd后台脚本执行是否完毕，非常直观的知道dd是否已经完成。

linux 环境下
#!/bin/bash
while true
do
DDRUN=$(ps -ef | grep dd | grep -v grep | wc -l)

if [ $DDRUN = 0 ] ; then

echo "--------------------------DD IS FINISHED OR NO DD---------------"

exit

else

echo "------------------------DD IS RUNING-----------------------------"
ps -ef | grep dd |grep if | grep -v grep | awk '{print $8,$9,"=",$10,$11,"=",$12,$13,$14}'
date

fi
sleep 10
done

HP unix环境下

#!/sbin/sh
while true
do
DDRUN=$(ps -ef | grep dd | grep -v grep | wc -l)
if [ $DDRUN = 0 ] ; then

echo "--------------------------DD Finished Or No DD Proccess---------------"

exit

else

echo "------------------------DD IS RUNING-----------------------------"
ps -ef | grep dd |grep if | grep -v grep | awk '{print $8,$9,$10,$11}'
date

fi
sleep 10
done
