powershell - Powershell cannot pass in command line string parameter

Question

\I have tried everything I can find on the web but I just can't make this work.... Really frustrating. All I want to do is to pass in a file name in the command line to my Powershell script test.ps1.

param([String]$input=$args[0])
$inputpath = 'C:\work\'
$inputfile = $($inputpath + $input+".txt")

I run the script like:

powershell .\test.ps1 "input"

However, the in the error message I print out, I keep getting "cannot find c:\work\.txt". Apparently my command line parameter isn't in there correctly. Can someone please help?

Answer 1

尝试更改$Input为其他名称。因为$Input用于管道变量。

Answer 2

我只是用它来构建路径：

$inputpath = 'C:\work\'
$inputfile = Join-Path $inputpath ($args[0] + ".txt")
