Fair enough. We somehow didn't read the gawk man page well enough to achieve the 
desired effect. Also I don't really see where the GNU grep authors draw the line 
between 'grep requirement' and 'grep feature' when I look at its man page to be 
honest.

Yes, we'll try to do that and see if it works with our command chain and the 
speical requirement of multiple pattern (mixed AND/OR/NEGATE) matching.

So as many of the options, I agree. It would be nice though to have an array of 
options one could specify for desired output, like it is done with the 'ps -o 
...' or top commands. So if you like to have POSIX required parsing and output, 
it will be the standard for portability reasons, everything else has the be done 
using the user-specific flags.

Thank you and best regards,
