异地备份拷贝脚本

#!/usr/bin/expect -f
#!/bin/sh
set passwd "123456"
set DATE [exec date +%Y%m%d]
spawn scp root@192.168.10.100:/home/shell/*$DATE*.tar.gz /home/test_DB_BAK
expect {
   "pass"
        {
          send "$passwd\n"
        }
   "yes/no"
        {
          sleep 5
          send_user "send yes"
          send "yes\n"
        }
   eof
    {
        sleep 5
        send_user "eof\n"
    }
}
set timeout 3000
send "exit\r"
expect eof
 

注意点：

1.执行脚本文件夹有可访问权限，通过chmod命令赋权限。

2.两台机器需有scp，spawn命令。

3.两台机器在同一个网段，网络畅通。
