ps

The PowerShell equivalent of the ps command is:

  1. get-process

You can use get-process to get information about other computers:

  1. get-process -ComputerName bigserver gvim*

You can use select and where to ‘slice and dice’ the information.

  1. get-process  | 
  2.   where {$_.PeakWorkingSet -gt 1Mb } | select ProcessName,PeakWorkingSet

As with ps, the get-process command has many options. This section of the e-book will be expanded over the next few months but, to start with, these are some of the ps examples from the Linux man page.

ps -ef (see every process on the system)

By default get-process shows all of the processes on the current PC or server

ps (show just current process)

If you wanted to just see details of your process you could do this:

  1. get-process -pid $PID

ps -ejH (print a process tree)

There is no PowerShell equivalent to the Unix ps -eJH, because as I understand it Windows processes aren’t part of a process tree.

ps -eLf (get info about threads)

I think this shows information about the processes threads:

  1. get-process -pid $pid | select -expand threads

ps -U (show particular user)

  1. get-process -IncludeUserName | ? Username -eq "Ronnie\Matt"

ps -ef | grep firefox

  1. get-process firefox

pwd

To show your current location in Powershell:

  1. Get-Location

…or there are aliases gl and pwd.

There is also a built-in variable

  1. $pwd
