$ lilypond source-file.ly |& tee /tmp/complete-errors | grep -v 'programming error: must have stem dir for note head' | grep -v 'continuing, cross fingers' Is this hackish enough? The unfiltered errors are available for consultation in /tmp/complete-errors. I would need sed rather than grep to filter out the second line only when preceded by this particular first line. Cheers, David.
