Help me please in writing a script - find a user with more processes running powershell.
I tried this option, but I'm not sure if the result is correct:
ps -IncludeUserName|? UserName -m "$env:USERNAME"

You can take the process objects you receive from Get-Process and use Group-Object to group them by UserName. Then sort the groups you get back by the Count property and Select only the last object which will be the group with the highest count of processes. Supplying -ExpandProperty Name will return only the Name property of the group which contains the UserName (which is what we grouped on using Group-Object)
Get-Process -IncludeUserName |
Group-Object UserName |
Sort-Object Count |
Select-Object -Last 1 -ExpandProperty Name
psreally an alias forGet-Process? You should be able to useGroup-Objectas a quick solution to this question. Also, the quotes around$env:usernameare not needed; although it is a good practice.m? You can't shorten-match.-matchin expression mode, but you can in argument mode, because with the simplified syntax being being used, the operators are simply (switch) parameters, and abbreviating parameter names works just fine, as long as the abbreviation is unambiguous. That said, the usual recommendation applies: use abbreviations only interactively, not in scripts.
