set Update=`ls -l /cjpgmserver/probe/log/${hostname} |awk '{print $8}'`  # 获取文件夹中的文件列表，并获取文件名

if($Update == `cat ${Maindir}Old_Time.log` && `cat /tmp/data.pcm |grep name |wc -l` == 5 && `cat ${Maindir}Before.log |grep Wafer |awk '{print $4}'` != `cat /cjpgmserver/probe/log/${hostname} |grep p1wafer |cut -d '=' -f2`) then
