Display the About files content in PowerShell
Although much of the help content in Windows PowerShell relates to commands, there are also many help files that describe PowerShell concepts. These files include information about the PowerShell scripting language, operators, and other details. This information doesn't specifically relate to a single command, but to global shell techniques and features.
You can review a complete list of these topics by running:
Get-Help about*
To view a specific topic, use:
Get-Help about_CommonParameters
You can also open the help topic in a separate window or online:
Get-Help about_CommonParameters -ShowWindow
Get-Help about_CommonParameters -Online
Note
For the -Online version to open, it must have the URI/URL included in the information in the local help files. If the URI/URL isn't included in the local version, you may receive an error.
When you use wildcard characters with the Get-Help command, About help files appear in a list when their titles contain a match for your wildcard pattern. Typically, About help files will appear last, after any commands whose names also matched your wildcard pattern. You can also use the ‑Category parameter to specify a search for About files.
Note
For much of this course, you'll need to refer to About files for additional documentation. You must review these files frequently to discover the steps and techniques you need to complete lab exercises.
