在ForEach循环中运行程序 [英] Run a program in a ForEach loop

问题描述

我正在尝试使此简单的PowerShell脚本正常工作，但我认为某些根本上是错误的. ;-)

I'm trying to get this simple PowerShell script working, but I think something is fundamentally wrong. ;-)

ls | ForEach { "C:\Working\tools\custom-tool.exe" $_ }

我基本上想获取目录中的文件，并将它们作为自定义工具的参数逐一传递.

I basically want to get files in a directory, and pass them one by one as arguments to the custom tool.

推荐答案

ls | %{C:\Working\tools\custom-tool.exe $_}

当每个对象沿管线下降时，将针对该对象运行该工具.在命令字符串两边加上引号会使它成为...一个字符串！这样，本地变量"$ _"很可能不知道如何处理，因此会吐出错误.

As each object comes down the pipeline the tool will be run against it. Putting quotes around the command string causes it to be... a string! The local variable "$_" it then likely doesn't know what to do with so pukes with an error.
