There was a message on the list > just recently that pointed to the exact locations for generating BOMs. Here's the command from my “update-partslist” script: gnetlist -g bom Schematic.sch -o Parts_List.tsv You need to create a file called “attribs” in the same directory as the schematic (or in the current directory? I'm not sure which, but in this case the schematic *is* in the current directory). value footprint description manufacturer manufacturer_partnum These five lines in the attribs file define which attributes will be used to select columns for the resulting tab-delimited output file.
