Basic Syntax

• Naming convention: Verb-Noun (Get-Process, Set-Content), unified and discoverable
• Parameter syntax: -ParameterName Value, supports short names and positional parameters; supports splatting (@params)
• Case sensitivity: Case-insensitive by default
• Comments:
  • Line comment: # ...
  • Block comment: <# ... #>
• Variables: Start with $ ($name), types are automatically inferred as needed
• Statements and blocks: {} represents script blocks, if/elseif/else, switch, for/foreach/while/do{}while, etc.
• Module loading: Import-Module; automatic module loading is handled by module manifest and command discovery mechanism
• Error types: Terminating and Non-terminating; $ErrorActionPreference controls behavior

Example: Parameter splatting with pipeline

$params = @{ Path='C:\temp\log.txt'; Value='hello'; Encoding='utf8' }
Set-Content @params
Get-Content $params.Path | Measure-Object -Line -Character

Script structure recommendations:

• Top comments describe purpose, parameters, examples
• Use [CmdletBinding()] and Param() to define advanced function parameters and pipeline binding
• Reasonable use of Write-Verbose/Write-Debug/Write-Information for controlled logging
