Are you implying that the Solaris and UnixWare grep doesn't support a 
leading carat as a line-beginning anchor?  I don't have a Solaris box in 
front of me but I'd be highly surprised if that was the case.  egrep 
(usually) adds support for things such as the () syntax, used for 
remembering previous matches and various other extended operations.  
What might be getting in your way would be shell differences, where ^ 
might be interpreted by the shell?  Perhaps you could try grep -c 
'^processor', or perhaps I'm thoroughly confused about what you believe 
isn't supported by the various non-GNU versions of grep.
