@achenle - The smaller reference file contains the 12 digit numeric reference for every active subscriber we have (format=000000000000). The much larger production file contains the 12 digit reference and an alphanumeric tariff code separated by a coma. Tariff codes have the following A000000 or AA00000 or A000000-AA00000 or AA00000-AA00000. The longer tariff codes indicate an additional service or add-on. So the format is 000000000000,A000000 or any other tariff/add-on variant

My aim is to extract the reference and tariff info from the production file, using the references contained in the accurate list.

@corona688 - The output of should be the same format as the production file which is reference,tariff ie 000000000000,AA00000. I don't think sorting is an issue at this point.

Guys thanks very much, I'll give it a go.

mmroff

MMROFF(1)                                                     General Commands Manual                                                    MMROFF(1)

NAME

       mmroff - reference preprocessor

SYNOPSIS

       mmroff [ -x ] groff_arguments

DESCRIPTION

       mmroff is a simple preprocessor for groff, it is used for expanding references in mm, see groff_mm(7).  groff is executed twice, first with
       -z and -rRef=1 to collect all references and then to do the real processing when the reference file is up to date.

       -x     Just create the reference file. This can be used to refresh the reference file, it isn't always needed to have  accurate  references
              and by using this option groff will only be run once.
