It is, however, conceivable that whatever naming convention you use for your linux hosts may indeed be regularly expressed in its entirety and without spurious matches. If absolutely necessary you could always add an additional step to your pipe:
... | grep <some regex capturing all potential Linux hosts> | grep -v <some regex eliminating spurious entries> | wc -l Naturally, the number of filters used is arbitrary. If it is more than three or four, though, it seems likely that your naming scheme is not particularly informative anyway.
