Command line export does not create an output bib file

[guillaumeparent]

JabRef version

5.9 (latest release)

Operating system

MacOS

Details on version and operating system

MacOS Ventura 13.0.1 (22A400)

Checked with the latest development build

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

I am trying to create sub-databases (one database by author) from a global .bib file using the filtering features of the command line tool. Here is the commande I use to filter only AuthorOneName related papers from the global Input_bib.bib file:

JabRef --exportMatches Author=AuthorOneName,Output_bib.bib,bib -i Input_bib.bib -n

I do not receive any error message, everything seems to be ok, including the filtering. Nevertheless, no output file is created.
Important information: it fails when using bib format as output, but it works for other formats such as bibtexml, endnote, html for instance.

Am I doing something wrong or is it a bug related to the bib format ?

Appendix

Input_bib.bib

@article{AutOne2022,
author = 	 {AuthorOneName, AuthorOneFirstName and AuthorTwoName, AuthorTwoFirstName},
title = 	 {An interesting paper},
journal = 	 {Mickey Mouse Magazine},
year = 	 {2023}
}

@article{AutTwo2023,
author = 	 {AuthorOneName, AuthorOneFirstName and AuthorTwoName, AuthorTwoFirstName},
title = 	 {Another interesting paper},
journal = 	 {Donald Duck Magazine},
year = 	 {2023}
}

@Article{AutThree,
  author  = {AuthorThreeName, AuthorThree3FirstName and AuthorTwoName, AuthorTwoFirstName},
  journal = {I love datahseets magazine},
  title   = {Look at this one},
  year    = {2021},
}

Sorry, OS was not good in the the description.

I could reproduce this. I found out that the "bib" format seems to match the EmbeddedBibTexExporter which will embed bib files into a pdf.
And second, I found out there is no BibTexExporter that could be used with the matcher option...
So I think you stumbled across an edge case that no one thought about before...
Will flag this as enhancement

Thank you for the answer.

But are you sure the issue is related to the matcher option ?
I tried to convert a .ris file into a .bib file, without filtering as follows and it did not create any output file either.
JabRef -o Output_bib.bib,bib -i Input_bib.ris -n

On another hand, I tried the same command but this time with a bibtexml as an output and it worked perfectly well.
abRef -o Output_bib.xml,bibtexml -i Input_bib.ris -n

So couldn't the issue be related to exporting a .bib file ?

I add the .ris file for reproduction purpose:

TY - JOUR
AU - AuthorOneName, AuthorOneFirstName
AU - AuthorTwoName, AuthorTwoFirstName
T1 - An interesting paper
JO - Mickey Mouse Magazine
Y1 - 2023
ER -
TY - JOUR
AU - AuthorOneName, AuthorOneFirstName
AU - AuthorTwoName, AuthorTwoFirstName
T1 - Another interesting paper
JO - Donald Duck Magazine
Y1 - 2023
ER -

From what I saw when you don't specify the output formant in the export command, it will use bibtex as default
