[Bug-datamash] datamash: selecting columns that include dashes

[Renato Alves]

Dear Assaf,

I'm trying to use datamash to aggregate and subset TSV data.
If I use integers for column identifiers everything works as expected.

$ datamash -H sum 2
sum(A_Chlor_T1h_r1-metaG)
22960

However if I try to specify column names datamash gets confused with the dash 
in the column name

$ datamash -H sum A_Chlor_T1h_r1-metaG
datamash: field range for 'sum' must be numeric

I tried different variations of single ('' or "") and double quoting ("''" or 
'""') as well as escaping ("\-" or '\-') but couldn't find a way to subset 
using the column name.
Since the order of columns is not maintained on all the files I'm using, using 
position-based indexing is unreliable.

Is there some syntax that allows selecting column names that contain dashes?
Additionally, is there any kind of support for wildcards when using column 
names? (i.e. something like "A_Chlor_T*")

Kind regards,
Renato
