shell中调用expect传值问题

水底游

1. [root@localhost expect]# cat f.sh
   
2. #!/bin/sh
   
3. while read i j
   
4. do
   
5. expect <<EOF
   
6. set ip $i
   
7. set password $j
   
8. set timeout 3
   
9. spawn ssh root@$ip
   
10. expect {
    
11. "*yes/no" {send "yes\r";exp_continue}
    
12. "*Password:" {send "$password\r"}
    
13. }
    
14. expect eof
    
15. EOF
    
16. done <ip.txt

执行后报错

1. [root@localhost expect]# ./f.sh
   
2. spawn ssh root@
   
3. ssh: Could not resolve hostname : Name or service not known
   
4. expect: spawn id exp4 not open
   
5.     while executing

预计是$i，$j的值没有传入进去

这个传值要怎么搞？

如果用单个文件直接写明ip的话是可以正常运行的

1. [root@localhost expect]# cat e.exp
   
2. #!/usr/bin/expect -f
   
3. set ip 192.168.1.212
   
4. set password qwe123
   
5. set timeout 10
   
6. spawn ssh root@$ip
   
7. expect {
   
8. "*yes/no" {send "yes\r";exp_continue}
   
9. "*Password:" {send "$password\r"}
   
10. }
    
11. interact
    
12. [root@localhost expect]#

我的脚本那么写，为什么不行的？参数转了两次不行还是什么原因的？
