cat no_bokmaal-ud-train.conllu | udpipe  --train nob.udpipe                  

Without tokeniser and tagger:

cat no_bokmaal-ud-train.conllu | udpipe  --tokenizer none --tagger none --train nob.udpipe                  

Parse some input

With gold standard POS tags:

cat no_bokmaal-ud-dev.conllu  |cut -f1-6 | sed 's/$/\t_\t_\t_\t_/g' | sed 's/^\t.*//g'| udpipe --parse nob.udpipe  > output               

Full pipeline:

echo "Det ligger en bok på bordet." | udpipe --tokenize --tag --parse nob.udpipe
