怎么判断获取spawn的进程是否正确执行

#!/bin/bash
>/root/cp_err.txt
for i in $(ls /root)
do
        expect << EOF
        spawn scp -r a $i 192.168.88.156:/home
expect {
        "ye/no" {send "yes\r"}
        "*password:" {send "root\r"}
}

set timeout 2
expect
expect "*"
send "BID=$?"
set timeout 5
EOF
if [[ "$BID" -eq  "0" ]]
then
echo "$i cp error" >> /root/cp_err.txt
fi
done


脚本执行后报错：
expect: spawn id exp4 not open
    while executing
"expect "*" "
spawn scp -r a 6.sh 192.168.88.156:/home
^Cspawn scp -r a anaconda-ks.cfg 192.168.88.156:/home
root@192.168.88.156's password:
a: No such file or directory
anaconda-ks.cfg                                                100% 2635     2.6KB/s   00:00   
Killed by signal 1.

怎么判断获取        spawn scp -r a $i 192.168.88.156:/home 是否正常执行也就是 这条命令的 $? 值，请大家帮下忙？谢谢
