Describe your issue

It is rather a question

Current behaviour of csvtk sort on an empty CSV is to return an non-0 exit code with [ERRO] no data to sort

Do you think it would be a good idea to rather not ERROR, but simply return same CSV with a [WARN] instead ?

This is already the behaviour of csvtk freq for example :

echo -e "c1,c2" | csvtk sort
# -> [ERRO] no data to sort

echo -e "c1,c2" | csvtk freq
# -> c1,frequency

Thank you

I'm grateful to users who have greatly helped to report bugs and suggested new features.

I may respond to issues or fix bugs quickly, but I usually implement new features periodically (two or more weeks).

Thanks to YOU for developping csvtk, it is a great tool !
