How to echo the field name using DSL?

[aborruso]

Hi,
I have this input CSV:

id,name
1,Andrea
2,Marco
3,Luigia

How to echo a field name, after cutting it, via DSL?

Currently I do it running this mlr --csv cut -f name input_01.csv | head -n 1, but I'm sure there is a super easy and obvious way to do it using some DSL code and put.

Thank you and forgive the stupid question

@aborruso how about

mlr --csv --from input_01.csv head -n 1 then put -q 'print(joinv(get_keys($*), ","))'

?
