Discovering Windows PowerShell Commands
Few people will master all of the PowerShell commands; however, you can master a basic self-discovery method used to learn and master any specific command. This method includes three important commands, as described in the following table.
| PowerShell Discovery Commands | Comments |
|---|---|
get-command [switches] PS C:\> get-command PS C:\> get-command -commandtype cmdlet PS C:\> get-command -commandtype alias PS C:\> get-command -commandtype function | The get-command cmdlet shows all of the possible commands. You can list the cmdlets, aliases, or functions separately as shown by the three examples. |
get-help get-help command [-full | -detailed | -examples] PS C:\> get-help set-executionpolicy -full PS C:\> get-help get-process -detailed PS C:\> get-help start-service -examples | The get-help command provides access to a rich set of built-in help.
You can follow get-help with the name of any command. By default, it provides basic help. However, you can also add the -full, -detailed, or -examples switches. The -detailed switch expands the basic information with more details and includes examples. The -full switch provides verbose help, including technical information. It includes all available help information including examples. It often includes online links for more information. The -examples switch shows a brief synopsis with examples. |
get-member command or object | get-member PS C:\> get-service | get-member $variable| get-member PS C:\> $profile | get-member | The get-member command provides information about properties and methods you can use with the command. Almost all of the commands are objects, meaning they have properties and methods. Properties are descriptions that you can retrieve and sometimes configure. Methods are actions you can take with the item. |
