PS sessions

PS sessions use Windows remoting to communicate between servers. PS sessions can be used for anything from remote command and script execution to providing a remote shell.

New-PSSession

Sessions are created using the New-PSSession command. In the following example, a session is created on a computer named PSTEST:

PS> New-PSSession -ComputerName PSTEST
Id Name ComputerName State ConfigurationName Availability
-- ---- ------------ ----- ----------------- ------------
1  Session1 PSTEST  Opened Microsoft.PowerShell Available

Get-PSSession

Sessions created using New-PSSession persist until the PS session is removed (by Remove-PSSession) or the PowerShell session ends. The following example returns sessions created in the current PowerShell session:

PS> Get-PSSession | Select-Object Id, ComputerName, State
Id ComputerName State
-- ------------ -----
 1 PSTEST       Opened

If the ComputerName parameter is supplied, Get-PSSession will show sessions created on that computer. For example...
