Feed pairs parameter file to compare and creatively pack/unpack compare output so that difference metric as well input parameters are displayed on the same line

xargs -0 -I '{}' -n 1 sh -c 'compare -metric MAE $1 -format "%[d]/%[f] %[o]" null: 2>&1 | tr "\n" "\t"' -- {} < <(tr \\n \\0 <pairs) | sed "s/\t\t/\n/g"
