Sorry about the sloppy code Roman,  the differences there don't matter

Does that matter?  I thought it was one of those situations where the 
dollar sign is optional.

Indeed.  I don't even know what the difference is.  I've never heard of 
slice assignment :(

The first version using sed.

Unfortunately not.  That works as you intend, but I need to filter not 
just colorize.  Any line without all matches must be deleted.  The 'for' 
loop runs the lines thru each filter in turn and must zero any line that 
does not match.

You can debug this by printing all relevant parameters.

Good idea!  That's going to be useful.
