PowerShell If Statements: IF equals multiple specific Texts

Looks like you're trying to create the directories if your user chooses one of 3 text phrases and the directory doesn't already exist, and complain to your user if they choose something other than the 3 text phrases. I would treat each of those cases separately:

$text = [Microsoft.VisualBasic.Interaction]::InputBox($msg, $title,"")$AcceptableText = @("Specific Text1","Specific Text2","Specific Text3")If ($text -in $AcceptableText){    If (!(Test-Path $Path\$text))     {        new-item -ItemType directory -path $Path\$text    }}Else{    write-host "invalid input"}

Or you could test for the existence of the directory first like this:

$text = [Microsoft.VisualBasic.Interaction]::InputBox($msg, $title,"")$AcceptableText = @("Specific Text1","Specific Text2","Specific Text3")If (!(Test-Path $Path\$text)){    If (($text -in $AcceptableText))     {        new-item -ItemType directory -path $Path\$text    }    Else    {        write-host "invalid input"    }}

EDIT: Or, if you want to be tricky and avoid the Test-Path (as suggested by @tommymaynard), you can use the following code (and even eliminate the Try|Catch wrappers if you don't want error checking)

$text = [Microsoft.VisualBasic.Interaction]::InputBox($msg, $title,"")$AcceptableText = @("Specific Text1","Specific Text2","Specific Text3")If (($text -in $AcceptableText)) {    try { mkdir -path $Path\$text -ErrorAction Stop } #Change to -ErrorAction Ignore if you remove Try|Catch    catch [System.IO.IOException] { } #Do nothing if directory exists    catch { Write-Error $_ }        }Else{    write-host "invalid input"}

EDIT: Also worth noting that there are many ways to Use PowerShell to Create Folders

Some nice, clean examples. Hope this helps.

Yes you can :) Note that in the switch statement, default is being executed when all the other cases are not matched. Please test it and let me know.

$text = [Microsoft.VisualBasic.Interaction]::InputBox($msg, $title,"")if (!(Test-Path $Path\$text)){    switch ($text)    {        "Specific Text1"        {            new-item -ItemType directory -path $Path\$text        }        "Specific Text2"        {            new-item -ItemType directory -path $Path\$text        }        "Specific Text3"        {            new-item -ItemType directory -path $Path\$text        }        default        {            write-host "invalid input"        }    }}

Start by worrying about the input validation separately from the Test-Path call:

$validValues = 'Specific text 1','Specific text 2','Specific text 3'$text = [Microsoft.VisualBasic.Interaction]::InputBox($msg, $title,"")if($validValues -notcontains $text) {    Write-Host "Invalid output"}elseif(!(Test-Path -LiteralPath $path\$text)) {    Write-Host "Item exists"}else {    New-Item -ItemType Directory -LiteralPath $Path\$text}
