使用 Powershell 运行 a.bat 脚本时避免“不被识别为内部或外部命令”

Question

I wrote a basic.bat script that you can find below:

@echo off
Add-Type -AssemblyName System.IO.Compression.FileSystem
function Unzip
{
    param([string]$zipfile, [string]$outpath)
    [System.IO.Compression.ZipFile]::ExtractToDirectory($zipfile, $outpath)
}
$import="E:\directory\import"
cd $import
Unzip $import\file1.zip $import\extract\
Unzip $import\file2.zip $import\extract\
Unzip $import\file3.zip $import\extract\

When I run these command lines directly into the PowerShell terminal (by copy-paste), it's working fine!

But, when I save all these command lines into a "test.bat" and - then - run this.bat file, it's not working:

Sorry, errors messages are in French, but it means "is not recognized as an internal or external command, executable program or command file" for each command line.

I've tried to run the.bat file from different ways:

1. .\test.bat directly into the directory from PowerShell terminal

2. [FULL_PATH]\test.bat

3. powershell E:\directory\import\test.bat from the CMD app

4. C:\windows\System32\WindowsPowerShell\v1.0\powershell.exe E:\directory\import\test.bat from the CMD app

5. Etc.

And I still get the same error messages.

You are mixing batch scripting and PowerShell Scripting. You need to save your script as a .ps1 file instead of a .bat and remove any cmd only commands.

test.ps1

Add-Type -AssemblyName System.IO.Compression.FileSystem
function Unzip
{
    param([string]$zipfile, [string]$outpath)
    [System.IO.Compression.ZipFile]::ExtractToDirectory($zipfile, $outpath)
}
$import="E:\directory\import"
cd $import
Unzip $import\file1.zip $import\extract\
Unzip $import\file2.zip $import\extract\
Unzip $import\file3.zip $import\extract\

The reason it works when copy pasting is because each command is interpreted independently and therefore can use different interpreters. However, this is not the case in a script in which the terminal must decide which interpreter to use. Based on the file extension, it chooses cmd. This only allows the @echo off to work and everything else will fail.
