grep throws in dashes?
Hey guys,

I'm trying to grep for two things out of a file and I got that working but why is it randomly throwing "--" in the output? Is there a simple way to get rid of them? It only seems to do it when the line above what im looking for has numbers in it.

Code:
$ egrep -i -B 1 'port-name|description' in.txt
127.0.0.1
