如何在Powershell中通过管道传输.exe执行的所有输出? [英] How to pipe all output of .exe execution in Powershell?

问题描述

在Powershell中，我正在运行psftp.exe，这是PuTTy的主页.我正在这样做:

In Powershell I am running psftp.exe which is PuTTy's homepage. I am doing this:

$cmd = "psftp.exe"
$args = '"username@ssh"@ftp.domain.com -b psftp.txt';
$output = & $cmd $args

这有效；我正在打印$output.但是它仅捕获该变量中的某些输出(例如远程工作目录为[...]")，并将其他输出抛出为这样的错误类型:

This works; and I am printing out $output. But it only catches some output in that variable (like "Remote working directory is [...]") and is throwing other output to an error type like this:

psftp.exe : Using username "username@ssh".
At C:\full_script.ps1:37 char:20
+         $output = & <<<<  $cmd $args
    + CategoryInfo          : NotSpecified: (Using username "username@ssh".:String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError

此正在使用用户名..."等看起来像普通的FTP消息.如何确保所有输出都放入$output?

This "Using username ..." etc looks like a normal FTP message. How can I make sure all output gets put into $output?

推荐答案

问题是某些输出被发送到STDERR，并且在PowerShell中重定向的方式与在CMD.EXE中不同.

The problem is some output is being sent to STDERR and redirection works differently in PowerShell than in CMD.EXE.

How to redirect output of console program to a file in PowerShell has a good description of the problem and a clever workaround.

基本上，以可执行文件作为参数调用CMD.像这样:

Basically, call CMD with your executable as a parameter. Like this:

我修复了我的代码，使其可以正常工作. :)

I fixed my code so it would actually work. :)

$args = '"username@ssh"@ftp.domain.com -b psftp.txt';
$output = cmd /c psftp.exe $args 2`>`&1
