what is the SI value in powershell ps?

1

I am trying to find process execution information with powershell ps. There is an attribute 'SI' whose values are usually like 0, 2, 10, etc. Specifically, I typed in the following to powershell: 

    PS C:\Users\> ps -pid 10860

Handles  NPM(K)    PM(K)      WS(K)     CPU(s)     Id  SI ProcessName                                                  
-------  ------    -----      -----     ------     --  -- -----------                                                  
    175      12    23068      12276       0.20  10860   2 geckodriver

Thanks! There is no code.
I could not find documentation for this SI attribute. Can anyone help ? Thanks

Thanks! There is no code.
Just a command line to powershell as follows. PS C:\Users> ps -pid 10860

This is the Session ID. Session 0 is shown for all services, Session 1 for first logged on user and 2 because you switch from user 1 to a new user logon.

I only have 1 user on my Tablet and so it shows session 0 for services and 1 for my user programs.

Thank you very much. Is there a way to know whether the processes are ready, running, sleep, zombie, etc., like in the ps of linux ? – Farn Wang – 2018-05-19T12:57:33.370

ps | Format-List * - this shows detailed data. Responding shows you true for running and false for suspended processes. – magicandre1981 – 2018-05-19T15:41:18.947

If you do a PS|Get-Member you'll see:

   TypeName: System.Diagnostics.Process

Name                       MemberType     Definition
----                       ----------     ----------
Handles                    AliasProperty  Handles = Handlecount
Name                       AliasProperty  Name = ProcessName
NPM                        AliasProperty  NPM = NonpagedSystemMemorySize64
PM                         AliasProperty  PM = PagedMemorySize64
SI                         AliasProperty  SI = SessionId
VM                         AliasProperty  VM = VirtualMemorySize64
WS                         AliasProperty  WS = WorkingSet64

...

So SI is an abbreviation for SessionID

Provided output comes from PS|Get-Member -MemberType AliasProperty. – JosefZ – 2018-05-19T08:25:47.267

@JosefZ In fact it was the complete output but snipped after the AliasProperties. The ...should denote that. The result is obviously the same. – LotPings – 2018-05-19T08:31:11.713

Thanks! Is there a way to know whether the processes are ready, running, sleep, etc., like the ps in linux ? – Farn Wang – 2018-05-19T12:57:08.590

Take a look at ALL properties and methods with an uncut ps|gm or ps powershell|fl * – LotPings – 2018-05-19T13:07:17.990
