如何从命令行请求用户输入（在从命令行运行脚本的同时）

Question

I have a PowerShell script named Script.ps1. This script has a Read-Host input prompt but I want to make the input BEFORE running the script.

For example:

C:\User\Desktop\Script.ps1 -input hello

This is the part of the script that requests the input:

$D = Read-Host -Prompt "Input here"

Answer 1

You can create a script file that prompts the user when parameter binding happens or at the command line.

Prompting User At Command Line:

Script.ps1 Contents:

param(
    [string]$in
)
"the input was $in"

Running the Script:

C:\User\Desktop\Script.ps1 -in (Read-Host "Input Here")

Output:

input here: Hello
the input was Hello

---

Prompting User During Parameter Binding:

Script.ps1 Contents:

param(
    [string]$in = (Read-Host "Input Here")
)
"the input was $in"

Executing Script:

C:\User\Desktop\Script.ps1

Output:

Input Here: hello
the input was hello
