@tost it's certainly a way to not write a long-sed-pattern (see above: pls don't print the other non-replaced lines + pls capture this thing + pls insert escape sequence + pls have ID and ID_FAMILY)

and is a good way to make your one "more robust" in the case that another 'debian' words appeared other than ID/IDFAM lines, u have to repeat the pattern a bit but is also nice and with more rigour :shibaheart:
