本文介绍如何使用SecureCRT的VBScript脚本实现自动登录并执行远程命令，包括连接和断开操作，适用于批量任务处理。

查看SecureCRT帮助文档：

Help-> Help Topics->Scripting -> Script Objects Reference -> Session Object

#$language = "VBScript"
#$interface = "1.0"

crt.Screen.Synchronous = True

' This automatically generated script may need to be
' edited in order to work correctly.

Sub Main
    for i = 0 to 100
    crt.Session.Disconnect
    crt.Session.Connect("/TELNET 192.168.1.1")
    crt.Screen.WaitForString "login:"
    crt.Screen.Send "root" & chr(13)
    crt.Screen.WaitForString "Password:"
    crt.Screen.Send "123456" & chr(13)
    crt.Screen.WaitForString "root@server:" 
    crt.Screen.Send "df" & chr(13)
    crt.Screen.WaitForString "root@server:" 
    crt.sleep 1000
    next
End Sub

上述脚本也可以把登陆部分放在for循环外面，只是在一台机器上反复执行一条命令隔1秒.

#$language = "VBScript"
#$interface = "1.0"
 
crt.Screen.Synchronous = True
 
' This automatically generated script may need to be
' edited in order to work correctly.
 
Sub Main
         Dim i
         i = 10
         Do While i > 0
                   crt.Screen.Send "df" & chr(13)
                   crt.Screen.WaitForString "root@server:"
                   crt.Screen.Send "echo ok" & chr(13)
                   crt.Screen.WaitForString "root@server:"           
                   crt.Sleep 1000
                   i=i-1
         Loop
End Sub

提示符root@ubuntu:~#,可以写成crt.Screen.WaitForString "root@ubuntu:"
crt.sleep 1000 'sleep 1 seconds

也可以自己录制一个脚本:Script-> Start Recording Script,停止，保存，运行即可。

CRT也支持Python，更加灵活。
