Question

I have a VBScript which Telnets into a Linux device and I would like to see the available memory. The following command produces an "Invalid procedure call or argument" error.

WshShell.SendKeys"df /mnt/cf | awk  /mnt/{print$2} "

如果我用人工电话进入该装置,并使用同一指挥系统,该装置就可运行。任何建议?

至今为止的法典:

Dim WshShell

Set WshShell = CreateObject("WScript.Shell")
WshShell.run"cmd" 
 *** open command window *** 
WScript.Sleep 250 WshShell.SendKeys("{Enter}") 
WshShell.SendKeys"telnet 10.13.2.2 -f VBSmemSize.txt" 
WshShell.SendKeys("{Enter}") 
WScript.Sleep 2000 
WshShell.SendKeys"root" 
WshShell.SendKeys("{Enter}") 
WScript.Sleep 1500 
WshShell.SendKeys"password" 
WshShell.SendKeys("{Enter}") 
WScript.Sleep 1500 
WshShell.SendKeys"df /mnt/cf |awk  /mnt/{print$2} " 
WshShell.SendKeys("{Enter}")

Answer 1

我不熟悉这项工作:

Dim oShell  

set oShell = wscript.createObject("wscript.shell") 

oShell.Run "df /mnt/cf | awk  /mnt/{print$2} "

Set oShell = Nothing

Answer 2

The error character is { , this is a special one. You could use {} to surround with those special character. For example,

WshShell.SendKeys"df /mnt/cf |awk  /mnt/{{}print$2{}} "
