Get-Help and Get-Command

Discover cmdlets before you guess.

Illustration for PowerShell
Lesson 1 is on the house.

PowerShell discovers itself: Get-Command lists cmdlets, functions, and aliases you can run.

Get-Help Get-ChildItem -Full shows synopsis, parameters, and examples for one command.

Get-Help item wildcards search names; -Online opens the current Microsoft docs page.

Prefer Get-Help over guessing parameter names — Wrong names fail loudly and waste time.

Tab-completion uses the same command metadata Get-Command exposes.
