如何将输出从CMD窗口重定向到文件 [英] How to redirect output from CMD window to file

问题描述

我编写了以下VBScript，以便在Linux计算机上从WIN XP运行命令并将输出命令重定向到out.txt文件(在C:\下)

I wrote the following VBScript in order to run commands from WIN XP on a Linux machine and redirect the output command to out.txt file (under C:\)

我不明白为什么命令窗口中的输出未写入out.txt文件.

I don’t understand why output from the command window is not written to out.txt file.

该行有什么问题

Sh.Run "cmd /k  & CMD >> ""C:\out.txt""" , 1, True

我的完整VB脚本:

'TARGET_HOST  - Linux machine

Const TARGET_HOST = "18.20.183.99"
const PATH =  "cat /etc/hosts" 
const LOGIN = "root"
const PASS = " dingdong "
Const PLINKPATH="""C:\SPUTNIK\plink.exe"""

Set Sh = CreateObject("WScript.Shell")

CMD = " echo y | " & PLINKPATH & " -ssh -pw " & PASS & LOGIN & "@" & " " & TARGET_HOST & " " & PATH 

Sh.Run "cmd /k  & CMD >> ""C:\out.txt""" , 1, True

Set Sh = Nothing

推荐答案

VBScript不会在字符串内部扩展变量.更改此:

VBScript doesn't expand variables inside strings. Change this:

Sh.Run "cmd /k  & CMD >> ""C:\out.txt""" , 1, True

对此:

Sh.Run "cmd /k " & CMD & " >> ""C:\out.txt""" , 1, True

最重要的是，您的命令格式错误.您需要在密码和用户名之间放置一个空格，并删除@和主机名之间的空格:

On top of that your command is malformed. You need to put a space between password and username, and remove the space between @ and hostname:

CMD = " echo y | " & PLINKPATH & " -ssh -pw " & PASS & " " _
  & LOGIN & "@" & TARGET_HOST & " " & PATH
