Is there a shorter way to pull groups out of a Powershell regex?

Question

In PowerShell I find myself doing this kind of thing over and over again for matches: ``` some-command | select-string '^(//[^#]*)' | %{some-other-command $_.matches[0].groups[1].value} ``` So basically - run a command that generates lines of text, and for each line I want to run a command on a regex capture inside the line (if it matches). Seems really simple. The above works, but is there a shorter way to pull out those regex capture groups? Perl had $1 and so on, if I remember right. Posh has to have something similar, right? I've seen "$matches" references on SO but can't figure out what makes that get set. I'm very new to PowerShell btw, just started learning.

Accepted Answer

You can use the `-match` operator to reformulate your command as:

```
some-command | Foreach-Object { if($_ -match '^(//[^#]*)') { some-other-command $($matches[1])}}
```
