Re: [Condor-users] exclude nodes via the condor_config?

["Smithies, Russell" <Russell.Smithies@xxxxxxxxxxxxxxxx>]

So if I want to exclude machines named imp56, imp57..imp63 I could do something like this?

    START != regexp("imp(56|57|58|59|60|61|62|63)@.*", Machine)

Or is there a better way of writing it?
