xshell自动化脚本_xshell脚本

xshell具有脚本功能，可以实现很多自动化的操作。

从xshell的官方手册，可以知道xshell的脚本分为3类：

xsh.Session

下面的函数或变量在xshell会话中使用，使用的时候要指定会话一起使用，比如使用Sleep()函数，要这样使用：xsh.Session.Sleep(1000)。

函数

变量

xsh.Screen

下面的函数和变量在处理xshell终端屏幕的时候使用，使用的时候要配合xsh.Screen一起使用，比如要使用Clear()函数，要这样使用：xsh.Screen.Clear

函数

变量

xsh.Dialog

使用的时候要配合xsh.Dialog一起使用，比如要使用MsgBox()函数，要这样使用：xsh.Dialog.MsgBox()

函数

按钮类型：

实例

Sub Main
    Dim hostname, username, password
    hostname = xsh.Dialog.Prompt ("Insert Hostname", "Prompt Dialog", "hostname", 0)
    username = xsh.Dialog.Prompt ("Username", "Prompt Dialog", "", 0)
    password = xsh.Dialog.Prompt ("Password", "Prompt Dialog", "", 1)

    if xsh.Dialog.MessageBox("Connect to " & hostname & " server", "MessageBox",1) = 1 then
        xsh.Session.Open("ssh://" & username & ":" & password & "@" & hostname)
    End If
End Sub

    xsh.Screen.WaitForString "Reboot now? (y/n)"    ' 等待目标设备发回 "Reboot now? (y/n)" 字符串  
    xsh.Screen.Send "y" & VbCr    ' 输入字符 y 并回车
