Playing around with Get-Help to find new and improved cmdlets<\/h2>\n
I love playing around with Windows PowerShell 3.0. On weekends and when I am traveling, I open the Windows PowerShell console and begin to explore. I always return to the three most basic cmdlets when I am exploring. The three basic cmdlets I use are Get-Help<\/b>, Get-Command<\/b>, and Get-Member<\/b>. A fourth one I always use is the Where-Object<\/b> cmdlet.<\/p>\n
Today, I decided to play around with Get-Help<\/b> and see where Windows PowerShell 3.0 was specifically mentioned. I decided to do the search because I remembered seeing some cmdlets being mentioned as introduced in Windows PowerShell 3.0. Here is the command I used.<\/p>\n
Get-Command -CommandType cmdlet | Foreach-Object { get-help $_ } |<\/p>\n
select name, description | where description -match “powershell 3.0”<\/p>\n
In this command (which is a single line command that I broke at the pipe character), I first use Get-Command<\/b> to return only cmdlets. I pipe the returned cmdlet info objects to the Foreach-Object<\/b> cmdlet and use Get-Help<\/b> to obtain Help from the cmdlets. Next, I use the Select-Object<\/b> cmdlet, and I choose the name and description where the description matches PowerShell 3.0.<\/p>\n
The output was a bit difficult to read, so I decided to autosize the output and wrap the lines. To do this, I use the Format-Table<\/b> cmdlet as shown here.<\/p>\n
Get-Command -CommandType cmdlet | Foreach-Object { get-help $_ } |<\/p>\n
select name, description | where description -match “powershell 3.0” | Format-Table -AutoSize -Wrap<\/p>\n
Now that I have something I can read, I noticed that the Help uses the same types of language all the time when introducing a new Windows PowerShell 3.0 cmdlet or when announcing a modification to a previously existing cmdlet. Here is the text that introduces new functionality for an existing cmdlet.<\/p>\n
Beginning in Windows PowerShell 3.0<\/p>\n
Here is the text that introduces a new cmdlet.<\/p>\n
This cmdlet is introduced in Windows PowerShell 3.0<\/p>\n
Note<\/b> Today I am talking about exploring Windows PowerShell 3.0 via Get-Help<\/b> and associated cmdlets. I am not writing a complete document that details all the changes in Windows PowerShell 3.0.<\/p>\n
I then begin to explore. First, I look for modified cmdlets by using the command shown here (this command is a single command that I broke on the pipe characters for readability).<\/p>\n
Get-Command -CommandType cmdlet | Foreach-Object { get-help $_ } |<\/p>\n
select name, description |<\/p>\n
where description -match “Beginning in Windows PowerShell 3.0” |<\/p>\n
format-table -AutoSize –Wrap<\/p>\n
The command and its associated output are shown here.<\/p>\n
Next, I look for new cmdlets. Here is the command I used.<\/p>\n Get-Command -CommandType cmdlet | Foreach-Object { get-help $_ } |<\/p>\n select name, description |<\/p>\n where description -match “This cmdlet is introduced in Windows PowerShell 3.0” |<\/p>\n Format-Table -AutoSize –Wrap<\/p>\n The command and its associated output are shown in the image that follows.<\/p>\n Hopefully this will get you started playing around with Windows PowerShell 3.0 It comes installed on Windows 8 and Windows Server 2012.
