新用户 powershell 获取服务

Question

这段代码有什么问题？

Clear-Host

$num1 = Read-Host "Please choose"

1 = service
2 = process
3 = pinging
4 = multiplying a number

$num1 = Read-Host " Please enter a number for service "
Snumber = 1
Get-Service

$num2 = Read-Host " Please enter a number for process"
$Number = 2
Get-Process

$num3 = Read-Host " Please enter a number to ping"
$Number = 3
$ComputerName = Read-Host "enter the FQDN of the target computer"
Test-Connection $ComputerName FQDN

$num4 = Read-Host " Please enter a number for double the number"
$Number = 4
$num4 = Read-Host "Pleas enter number 5" 
Write_Host "Your original number was 5, now it's 10"`enter code here`

为什么脚本不尊重用户的选择？ 为什么它在循环？ 脚本没有 ping。 我希望用户选择一个数字然后任务完成并且光标回到问题请选择一个数字？很快 我不希望它完成任务后转到下一个问题

你的代码块有很多错误，所以我只是用我相信你正在努力完成的内容重写了其中的 90%。

# Sets up the visual choices for the user
Function Choose-Selection {
    Clear-Host

    Write-Host "1: Service"
    Write-Host "2: Process"
    Write-Host "3: Pinging"
    Write-Host "4: Multiplying a number"
    Write-Host "Q: Quit" -ForegroundColor Red 
}

# Displays those choices
Choose-Selection
# Enters loop
Do{
    # Checks for a selection from the user
    $selection = Read-Host "Please make a selection"
    # Switches take the input from the user and runs code based on the switch
    Switch($selection) {
        '1' {
            $num1 = Read-Host " Please enter a number for service"
            (Get-Service)[$num1]
            Sleep -Seconds 5
            Choose-Selection
        } '2' {
            $num2 = Read-Host " Please enter a number for process"
            (Get-Process)[$num2]
            Choose-Selection
        } '3' {
            $ComputerName = Read-Host "enter the FQDN of the target computer"
            Test-Connection -ComputerName $ComputerName
            Sleep -Seconds 5
            Choose-Selection
        } '4' {
            $num4 = Read-Host " Please enter a number for double the number"
            # Checks to see if input is an int. If not an int, terminates script
            If($num4 -match '^[0-9]+$') {
                "Your original number was $num4, now it's $([int]$num4*2)"
            } Else {
                Throw "You have not entered a valid number. Menu terminated."
            }
            Sleep -Seconds 5
            Choose-Selection
        } 'q'  { 

            'Leaving Menu...'
            Return
        }
    }
 }

Until($response -eq 'Q')

我看到的你的问题。

# This section does nothing except cause errors
1 = service
2 = process
3 = pinging
4 = multiplying a number

# What is SNumber? Variables need a $ in front of them
$num1 = Read-Host " Please enter a number for service "
Snumber = 1
# What are you doing with the number they give you? You are retrieving all services
Get-Service

$num2 = Read-Host " Please enter a number for process"
$Number = 2
# What are you doing with the number they give you? You are retrieving all Processed
Get-Process

$num3 = Read-Host " Please enter a number to ping"
# What is this variable used for?
$Number = 3
$ComputerName = Read-Host "enter the FQDN of the target computer"
Test-Connection $ComputerName FQDN

$num4 = Read-Host " Please enter a number for double the number"
# What is this variable used for?
$Number = 4
$num4 = Read-Host "Pleas enter number 5" 
# What if I chose the number 200, it will still say I chose 5
# Well it would if it didn't error out. The command is Write-Host
Write_Host "Your original number was 5, now it's 10"`enter code here`
