Powershell Windows

PowerShell's syntax can bite you in ways other shells don't, and this skill exists to prevent those bites. It covers the critical gotchas like mandatory parentheses around cmdlets when using logical operators, the strict ASCII-only requirement that breaks if you use emoji or Unicode, and null checking patterns that prevent runtime explosions. You also get error handling conventions, the essential Depth parameter for JSON operations, and a clean script template. If you're working with Windows automation or find yourself debugging cryptic "unexpected token" errors, this reference cuts through the trial and error. It's the distilled pain of everyone who learned PowerShell the hard way.
