Continuing the series looking at new cmdlets available in PowerShell 2.0. This time we look at the Get-PSSession cmdlet.
What can I do with it?
Retrieve remote PowerShell sessions created in the current session.
Examples:
Get all current sessions
Get-PSSession
Get session 3.
Get-PSSession -Id 3
Get all sessions open with Test01. (Not well illustrated in this screenshot since there is only one server with sessions open, but you get the idea)
Continuing the series looking at new cmdlets available in PowerShell 2.0. This time we look at the New-PSSession cmdlet.
What can I do with it?
Establish a persistent connection to a computer that has been enabled for PowerShell remoting.
Examples:
Establish a persistent remote PowerShell connection to Test01 and store it in the variable $session. Then use the Enter-PSSession cmdlet with the Session parameter to use that session.
$session = New-PSSession -ComputerName Test01 Enter-PSSession -Session $session
Continuing the series looking at new cmdlets available in PowerShell 2.0. This time we look at the Invoke-Command cmdlet.
What can I do with it?
Run commands on local or remote computers and return the results.
Examples:
Establish a persistent remote PowerShell connection to Test01 using New-PSSession and store it in the variable $session. Then return the results for which services begin with T.
$session = New-PSSession -ComputerName Test01 Invoke-Command -Session $session -ScriptBlock {Get-Service | Where-Object {$_.
Continuing the series looking at new cmdlets available in PowerShell 2.0. This time we look at the Enter-PSSession cmdlet.
What can I do with it?
Open an interactive PowerShell session with a computer which has been enabled for PowerShell remoting.
Example:
Open a session with the server Test01 and see which services begin with the letter T.
Enter-PSSession -ComputerName Test01 Get-Service | Where-Object {$_.name -like ‘T*’}
You will notice that the prompt has changed to
Continuing the series looking at new cmdlets available in PowerShell 2.0. This time we look at the Exit-PSSession cmdlet.
What can I do with it?
Exit an interactive PowerShell session that has been opened on a computer which has been enabled for PowerShell remoting.
Example:
Leave an interactive PowerShell session with a computer which has been enabled for PowerShell remoting.
Exit-PSSession
You will notice that the prompt has changed back from
Continuing the series looking at new cmdlets available in PowerShell 2.0. This time we look at the Enable-PSRemoting cmdlet.
What can I do with it?
Configure a computer to be enabled for PowerShell remoting. Tip: Make sure you run this cmdlet from an elevated process.
Example:
Configure the computer Test01 to be enabled for PowerShell remoting.
Enable-PSRemoting
This will produce output similar to the below; note the command was run on a Windows Server 2008 64bit system
Continuing the series looking at new cmdlets available in PowerShell 2.0. This time we look at the Import-Counter cmdlet.
What can I do with it?
Create objects by importing performance data in BLG, CSV or TSV files.
Example:
Import as objects data in a BLG file previously exported from Export-Counter or the Performance Monitor GUI.
$performancedata = Import-Counter -Path Memory.blg
How could I have done this in PowerShell 1.0?
To manage performance data contained in a BLG file you could have used the Performance Monitor GUI to import it and view the contents.
Continuing the series looking at new cmdlets available in PowerShell 2.0. This time we look at the Export-Counter cmdlet.
What can I do with it?
Take performance objects generated from the Get-Counter or Import-Counter cmdlets and export them as log files. Note: this cmdlet requires Windows 7 or Windows Server 2008 R2 or later.
Examples:
Retrieve some memory performance data from the local machine and export it to the standard Performance Monitor output file BLG.
Continuing the series looking at new cmdlets available in PowerShell 2.0. This time we look at the Test-ComputerSecureChannel cmdlet.
What can I do with it?
Test the secure channel between the local computer and the domain and optionally fix if necessary.
Example:
Test the secure channel on the current computer
Test-ComputerSecureChannel
Note: this will return a Boolean value of True or False as seen below; if you wish for more detailed information use the -Verbose parameter.
Continuing the series looking at new cmdlets available in PowerShell 2.0. This time we look at the New-WebServiceProxy cmdlet.
What can I do with it?
Make use of an available web service.
Examples:
The website http://www.webservicex.net has a number of available web services which you can use with the New-WebServiceProxy cmdlet.
Find the current weather for Southampton, UK.
$weather = New-WebServiceProxy -uri “http://www.webservicex.net/globalweather.asmx?wsdl" $weather.GetWeather(‘Southampton’, ‘United Kingdom’)
Note: to find what cities were available within the UK to query I used the GetCitiesByCountry method.
