You should.
At least after having read:
get-help about_regular_expressions
or the online version

^ means that pattern must match at string begining.

alternatively,
gc servers | Where-Object {$_.StartsWith("#") -eq $false}

should work too

^ Matches the beginning "book" -match "^bo"
characters

And it's get-help about_regular_expression ' No s at the end.

I figured I'd mention you could do it in one command with select-string...

select-string '^(?!#)' file.txt

Well to be unambiguous
get-help about_reg
is sufficient,
but PowerShell V2 from Windows 7 where I copied the whole line from has the
s at the end.
