How to use adb shell command to check path exist in Android Emulator with PowerShell

Question

I am new to Powershell, and I want to check if specfic path exits in Android emulator, I need to use it in PowerShell. I try to print the result of adb shell ls /data/local/tmp/, it will list files, and if the path does not exist, it will show No such file, but how to detect it? Any one knows?

I think the link does not contain the answer to my question, thank you anyway — newszer, Jan 17 '18 at 06:25
So: https://stackoverflow.com/questions/11526285/how-to-count-objects-in-powershell ? It may help to edit your question with what you've written already. — Morrison Chang, Jan 17 '18 at 06:28
so what do you want to achieve actually? to test on your android device if the given directory exist? if so, what then? — pskink, Jan 17 '18 at 06:31
Thank you Morrison, I try your approach, it works in most cases, because the count I get when file does exits is 2, but when the path exists and it contain 1 file the count is also 2. So I think I need to some deeper detect. — newszer, Jan 17 '18 at 06:39
Hi pskink, yes I want to detect whether the path exist in android device, but it is needed to detect it in an Powershell script. — newszer, Jan 17 '18 at 06:40

Actually I have found my way to check it

 $checkPathExists = (adb shell ls $pathToCheck) | Out-String
if($checkPathExists -match 'No such file or directory')
{
    Write-Host "$pathToCheck path does not exist. Try to create it ..." -ForegroundColor Red
    adb shell mkdir $pathToCheck
    if(!$?)
    {
        Write-Host "Creating $pathToCheck folder failed!" -ForegroundColor Red
        exit 1
    }
}

Validaitng paths are done using the Test-Path cmdlet on Windows/OSX/Linux.

Get parameter, examples, full and Online help for a cmdlet or function

(Get-Command -Name Test-Path).Parameters
Get-help -Name Test-Path -Examples
Get-help -Name Test-Path -Full
Get-help -Name Test-Path -Online

Then just use If/Then, Try/Catch to perform actions based on your needs.
