title: Can I have powershell scripts in file with no extension?
body: <p>Usually powershell script files end with .ps1, and modules end with .psm1.</p>
  
  <p>Can one have powershell scripts/modules in files with no extension? Just "build" or "start" and so on? Will this cause an issue in any specific environment? </p>
  
  <p>If yes, Can one have powershell scripts/modules in files with other "texty" extensions like .sh, .ps etc?</p>
  
  <hr>
  
  <p>Is there an easier way to invoke powershell scripts instead of keying in .\script.ps1 arg1, arg2 , for example like : go arg1, arg2?</p>
