  What have you tried?

  You can use Select-String to find a string in a file:

  help select-string -full

  Hi Jon,

  here is an example:

  $text = Get-Content D:\test1.txt
  $prompt = Read-Host -Prompt 'number '
  if($prompt -in $text)
  {
      Write-Host 'welcome!' -ForegroundColor Green
  }else{
      Write-Host 'please try again...' -ForegroundColor Red
  }
  
  

  Best regards,

  Andy

  I want to do a loop that keeps checking for a match until its in the txt file.

  If that's really the requirement you could use an "until loop" and check in every cicle if the pattern matches.

  That could help you: PowerShell Looping: Understanding and Using Do…Until ... the rest you've already got from Andy.
