PowerShell: Is there an automatic variable for the last execution result?

Question

I\'m looking for a feature comparable to Python interactive shell\'s \"_\" variable. In PowerShell I want something like this:

> Get-Something # this returns          


        

Answer 1

How about invoking the last command with "r" (alias for Invoke-History) and wrapping it in parentheses() to execute it first?

Yes this reruns the last command, but in my use cases this is by far the most streamlined solution especially for times when I don't realize that I'll need the last commands output at first.

It also keeps the object structure intact.

PS C:\Users\user> Get-NetAdapter -InterfaceIndex 3 | Where {$_.State -match "2"}

Name                      InterfaceDescription                    ifIndex Status       MacAddress             LinkSpeed
----                      --------------------                    ------- ------       ----------             ---------
Ethernet                  Intel(R) Ethernet Connection I217-LM          3 Up           XX-XX-XX-XX-XX-XX       100 Mbps

PS C:\Users\user> (r) |where {$_.LinkSpeed -eq "100 Mbps"}
Get-NetAdapter -InterfaceIndex 3 | Where {$_.State -match "2"}

Name                      InterfaceDescription                    ifIndex Status       MacAddress             LinkSpeed
----                      --------------------                    ------- ------       ----------             ---------
Ethernet                  Intel(R) Ethernet Connection I217-LM          3 Up           XX-XX-XX-XX-XX-XX       100 Mbps

PS C:\Users\user> (r).MacAddress
Get-NetAdapter -InterfaceIndex 3 | Where {$_.State -match "2"}
XX-XX-XX-XX-XX-XX
