Kicad CLI : Exporting BOM does not work with ${QUANTITY}

[mexok]

I am using the following command to export a BOM from a schematic:

 kicad-cli  sch export bom \ 
  --fields "Reference,Value,${QUANTITY}" \
  --exclude-dnp --group-by "Value" test.sch

However, the ${QUANTITY} field does nothing. The output csv does not have the Quantity column.

How do I get Quantity in the CSV.
Thanks.

EDIT1: Explicitly specifying the default does not work either, like this:

kicad-cli  sch export bom --fields "Reference,Value,Footprint,${QUANTITY},${DNP}" --exclude-dnp --group-by "Value" test.sch

EDIT2: Removing the --fields field makes the default (incl quantity) work.

kicad-cli  sch export bom --exclude-dnp --group-by "Value" vet-tx.kicad_sch && head vet-tx.csv

When you quote a command line argument with " (double quote) the shell will expand expressions of the form $VAR or ${VAR}. Use ’ (single quote) or escape the $.

Thank you so much.
That was obvious once you pointed it out
