One could also try:
Code:
awk 'FNR == 1 { fc++ } fc < 3 {d[$0]; next } !($0 in d)' DIFF MATCH ALL

which has been tested.

This requires enough space for the unique records in DIFF and MATCH to be held in memory, but doesn't require space in memory for the unique records in ALL.

       fc-match [ -svV? ] [ --sort ] [ --verbose ] [ --version ] [ --help ] [ font-pattern ]

DESCRIPTION

       fc-match  matches  font-pattern	(empty pattern by default) using the normal fontconfig matching rules to find the best font available.	If

       otherwise only the file, family and style are printed..

       below.

       -v --verbose
	      Print whole font pattern for each match.

       -? --help
	      Show summary of options.

       -V --version
