If you don't mind me asking here a couple of questions which I've searched over on google but was unable to find some coherent examples.

My use case contains of creating .bib files for my work and occasionally merge them to a bigger .bib file. The citekeys I use are of the following pattern author_year_unique_consecutive_letter, (in case of multiple publications from same author in the same year) without the underscores.

Example:

doe2018

doe2018b

doe2018c

doe2018d

etc...

I would like eventually to achieve the following when merging .bib files to the main bigger one.

1) search all entries in the separate .bib files and if there's a missing field such as for instance journal then add a user defined text

I tried the following command looking at the manual of bibtool but seems not to produce the desired output.

bibtool 'add.field={journal="(journal){%N(journal)}{--no-journal--}"}' ./biblio.bib

2) before merging everything to the bigger .bib file check for duplicate entries, meaning find entries where they have the same key and same title and resolve those by deleting the excessive entries, in the case where there's only duplicate keys but the titles among those entries are different then extract those entries and dump them in an additional file called duplicates.bib for manual inspection, avoiding merging them altogether in the bigger .bib file.

Thanks!
