请教expect定义IP地址数组，然后远程执行命令。

cnid123456

我已经写好了一个脚本，但是不知道怎么能把IP定义一个数组，然后分别去远程SCP执行命令，目前是一个一个IP改脚本反复执行的，实在是太笨了。

1. #!/usr/bin/expect -f
   
2. set remote "192.168.137.100"
   
3. set local "192.168.137.102"
   
4. set passwd "123456"
   
5. set passwd1 "qwerty"
   
6. spawn ssh matao@$remote;
   
7. expect {
   
8. "*yes/no*" { send "yes\r"; exp_continue}
   
9. "*password*" { send "$passwd2\r" }
   
10. };
    
11. expect "*@*";
    
12. send "su -\r";
    
13. set timeout 10
    
14. expect "*password*";
    
15. send "$passwd\r";
    
16. expect "*@*";
    
17. send "netstat -ntpla |grep LISTEN > /root/aaa.txt\r";
    
18. expect "*@*";
    
19. send "scp /root/aaa.txt root@$local:/root/$iphost.txt\r";
    
20. set timeout 10
    
21. expect {
    
22. "*yes/no"    { send "yes\r"; exp_continue }
    
23. "*password*" { send "$passwd\r"; exp_continue }
    
24. };
    
25. expect {
    
26. "*password*"    { send "$passwd1\r" }
    
27. };
    
28. expect "*@*";
    
29. send "rm -rf /root/aaa.txt\r";
    
30. expect 100%;
    
31. expect eof;

1. set all ip in a file (ex: ip.txt)
192.168.137.100
192.168.137.101

2. write a shell script to read each ip with while loop and call the expect script with ip argument
while read ip
do
  cmd="./scp_ip.exp $ip"
  echo "cmd=$cmd"
  $cmd
  # or run it in background by $cmd &
done < ip.txt

3. get remote ip from command first argument in expect script

set remote [lindex $argv 0]
send_user "  IP=$remote\n"

Note: you have to add more function in your expect
1. to record into a log file
2. date time information

有遍历数组的方法吗？

为什么一定要 数组?

for ip in $(cat ip.txt); do
    : do something
done

数组好，只用到执行文件，不会多出一个文件来。
