PowerShell Windows — Scripting Rules

Core Principles

1. Command Separation

• Windows PowerShell 5.1 does not support &&; PowerShell 7 does.
• For independent commands use ;: Set-Location "path"; Get-ChildItem.
• For dependent native commands preserve short-circuit semantics explicitly:

  git add .
  if ($LASTEXITCODE -eq 0) { git commit -m "message" }
  

2. Path Quoting

• Always use double quotes for paths with spaces:

  cd "D:\My Projects\MyApp"
