shell中调用expect小例子

#mysql_file1='refund*.gz'
hosts=`cat all.hosts`
logname='/tmp/expect.log'
rm -rf $logname
for i in $hosts;
do
#     echo $ipadd
        ipadd=`echo $i|awk -F, '{print $1}'`
        password=`echo $i|awk -F, '{print $2}'`
        cine_name=`echo $i|awk -F, '{print $3}'`
        expect -c"
        set timeout 600
        spawn /usr/bin/scp -l 1024 $ipadd:${code_path}${mysql_file} /root/wzp/all/
        log_file $logname
        expect {
                        \"*yes*\" {send \"yes\r\"; exp_continue}
                        \"*password*\" {send \"$password\r\";}
        }
        expect eof;"
