Create a persistent session and run multiple commands over it.

Run $s = New-PSSession -ComputerName host, then pass -Session $s to each command.

01Command

Command

$ $s = New-PSSession -ComputerName server01; Invoke-Command -Session $s -ScriptBlock { Get-Date }; Remove-PSSession $s

02What it does

Each Invoke-Command normally opens and closes a connection, but a named PSSession is established once and reused, which reduces authentication overhead and preserves state such as imported modules. Persistent sessions are essential when automating several steps against the same host.

!Warning: Idle sessions hold resources on both ends; close them with Remove-PSSession when the script finishes.
