Powershell matching by two values

I try to get all Processes with starting letter w or s

Something like this:

Get-Process | Where-Object ProcessName -Match "^w.*" -or ProcessName -Match "^s.*" | Select-Object name, ID

but this doesnt work.

Get-Process supports wildcards in the ProcessName parameter, so in this case you don't need Where-Object:

Get-Process -ProcessName '[ws]*' | Select-Object Name, ID

For complex expressions that use the same operator more than once or require logical operators, you need to pass a script block to Where-Object:

Get-Process | Where-Object { $_.ProcessName -Match "^w.*" -or $_.ProcessName -Match "^s.*" } | Select-Object name, ID

Though in this case, you don't really need a complex expression, as Mathias R. Jessen has pointed out.

Since it's either one or the other, in the same position, you can use character class group ([characters]):

Get-Process | Where-Object ProcessName -match '^[ws]' | ...

The .* at the end of either pattern is moot.
