Powershell

These build intuition for how PowerShell objects behave.

• Get-Command — Find commands by name, verb, or module
• Get-Help <cmd> -Online — Open full docs in browser
• Get-Member — Inspect object properties/methods
• Get-Module -ListAvailable — See what’s installed
• Import-Module — Load modules explicitly

Perfect for modular utilities that need predictable path handling.

• Get-ChildItem (ls) — Enumerate files/folders
• Resolve-Path — Convert relative → absolute
• Join-Path — Safe path concatenation
• Test-Path — Check existence
• New-Item / Remove-Item — Create/delete files or folders
• Copy-Item / Move-Item — File operations

These are the backbone of clean, signature output.

• Where-Object — Filter objects
• Sort-Object — Sort by property
• Select-Object — Choose or rename properties
• Format-Table -AutoSize — Clean tabular output
• Format-List * — Full detail dump

Your tactical debugging zone.

• Test-NetConnection — Ping, port tests, traceroute
• Resolve-DnsName — DNS lookup
• Get-NetAdapter — NIC info
• Get-EventLog / Get-WinEvent — Event logs
• Get-Process / Stop-Process — Process control
• Get-Service / Restart-Service — Service management

These commands matter when building modular systems.

• Read-Host — Prompt for input
• Write-Output / Write-Host — Output control
• Start-Job / Receive-Job — Background tasks
• Start-Process — Launch external apps
• Invoke-Expression — Execute dynamic code (use sparingly)
• Invoke-RestMethod — API calls
• Invoke-Command — Remote execution

Useful for utilities that need secure handling.

• Get-Credential — Secure credential prompt
• ConvertTo-SecureString — Encrypt strings
• Export-Clixml / Import-Clixml — Secure credential storage
