一个简单的循环rsync是否同步完成脚本

用rsync来同步文件，有时会碰到网络等问题同步未完成，写了个简单的循环判断，若同步失败则每隔5分钟再去同步

#!/bin/bash

date=`date +%F`

rsynclog=/home/data/log/rsync$date.log

echo `date` >> $rsynclog

/usr/bin/rsync -azP -e ssh *.*.*.*:/data/wd/HYZX* /home/data >>$rsynclog 2>&1

sleep 5

var1=`cat $rsynclog |awk 'END {print $1}'`

var2=`tail -2 $rsynclog |head -n 1 |awk '{print $1}'`

sucess="${var1}${var2}"

while [ "$sucess" != "totalsent" ]

do 

echo `date` >> $rsynclog

/usr/bin/rsync -azP -e ssh *.*.*.*:/data/wd/HYZX* /home/data >>$rsynclog 2>&1

sleep 300

var1=`cat $rsynclog |awk 'END {print $1}'`

var2=`tail -2 $rsynclog|head -n 1 |awk '{print $1}'`

sucess="${var1}${var2}"

done
