Jeffery Snover encourages us to explore PowerShell, spelunking I believe he calls it. Spelunking is the art of cave exploring the Urban dictionary has other definitions NSF. Spelunking is pursued due to the great enjoyment practitioner’s experience, Snover wants us to experience the same joy with PowerShell.
Steve Knutson editor of the National Speleological society termed the untrained and inexperienced as a ‘spelunker’ and denoted those who were trained and experienced ‘cavers’. Our goal is to go from Spelunker to PowerSheller, I suppose spelunkers probably wear the title like some of us wear the title hacker, and those who see the term as derogatory. For my Brothers in the UK I believe the correct term is Potholer, and you say we yanks screw up the language..
Spelunkers have tools helmets, head lamps, rope, knee and elbow pads and apparently cups thanks @jsnover. These tools help them explore the caves they seek out. PowerShellers have tools too, Get-Help, Get-Command, Help about_*, and don’t forget the helmet or -Whatif and cup -CONFIRM which are parameters which let you explore safely. Get-Help along with Help about_ are like guidebooks written by the original explorers.
This article will teach the basic use of these tools let’s enter the cave.
Down the Rabbit Hole
Get-Command think of get command as the flashlight which let’s you see in the dark. Caves have features Powershell has cmdlets. These cmdlets follow a basic semantic pattern of verb+noun.
Get-Command #alias GCM
Get-Help Get-Help allows you to further explore commands once you’ve discovered them. Get-Help is like the guidebook that helps you navigated an already discovered cave feature.
Get-Help Get #Alias Help Man
Get-Verb Gets the list of approved verbs. You can find guidance here https://msdn.microsoft.com/en-us/library/ms714428(v=vs.85).aspx . They get pretty pissy if you deviate… For good reason. Although I wonder if they have a User voice for dictionary adds.
Cavers write guides and maps to the caves they have explored and for PowerShell this guidebook is Get-Verb.
Entering Get-Verb at the PowerShell prompt yields the following truncated, for space ,results.
Get-Verb Verb Group ---- ----- Add Common Clear Common Close Common Copy Common Enter Common Exit Common Find Common Format Common Get Common Hide Common Join Common Lock Common Move Common New Common
Help About_* IF Get-Command is a flashlight, the about _* is the full guidebook. The About topics cover the core topics and concepts of PowerShell. About topics are part of the help system
Helpful comment from the father of PowerShell in terminology
-Whatif Put on your helmet and add this to parameter as you crawl to end of your Pipeline.
Set-ADForest -Windows2012Forest -Whatif
-Confirm Definitely a cup it’s your last form of protection from a mistake that could indeed leave you breathless
Set-ADForest -Windows2012Forest -Confirm
These are the basic commands to let you explore the cave that is PowerShell.
The cavers Guidebook to PowerShell starts with Learn Windows PowerShell in a Month of Lunches, Third Edition Don Jones@ and Jeff Hicks @ . Note this is a MEAP which means the book is being published in chapters. The 2nd Edition can be found on the same site.
