Пример странного поведения awk:

[peet@acer rt-network]$ echo "interface ethernet 0" | awk '{gsub(/ethernet[[:blank:]]+([0-9]+)/,"eth\1"); print $0}'
interface eth
[peet@acer rt-network]$ echo "interface ethernet 0" | awk '{gsub(/ethernet[[:blank:]]+([0-9]+)/,"eth\\1"); print $0}'
interface eth\1
[peet@acer rt-network]$ echo "interface ethernet 0" | awk '{print gensub(/ethernet[[:blank:]]+([0-9]+)/,"eth\1","g")}'
interface eth
[peet@acer rt-network]$ echo "interface ethernet 0" | awk '{print gensub(/ethernet[[:blank:]]+([0-9]+)/,"eth\\1","g")}'
interface eth0

Кто что может сказать на эту тему? Или "очередное злодейство в виде расширения gnu"
отключили, мол, ну никак не должен awk оперировать бэкреференсами в gsub? ;)

Вешать багу? Или само срастётся?
