english is fine. can you confirm that '/^default/ s/^default.*dev //'
is a suttered way to say 's/^default.*dev //' ?

i realize i assumed in the first place that 'default dev' was the only
valid part but i just saw there can be a 'via something' subpart.
> 1. Take the first line.
that's what i was afraid about. does ip r garanty that? my version was
sed '
/^default.*dev /!d # do nothing until you find a match
# so the next commands applies only on the valid line
s///d # remove what you just found
s/ .*//d # remove the tail of the sentence
q # print and quit
'
Regards
