No. > More general, is > there a way to set the separator to other transitions? Not yet as there hasn't been sufficient need for it. Currently, both `join` and `sort` take the -t option to specify a field separator _character_. There was a related change in `join` since v8.4-17-gf86bb69 where -t '' is used to match on the whole line (which aligns with the default operation of sort). When implementing multi-byte character support for join (not yet merged) I ensured that multiple bytes where allowed only when they corresponded to a single character so that in future we might support higher level functions like '[:class:]' cheers, Pádraig.
