Classificação da versão do Linux; letras primeiro

Question

O GNU sort -V é ótimo para classificar endereços IP. Infelizmente, ele lança todas as linhas com letras iniciais (em oposição a números) na parte inferior da pilha. Existe uma maneira de contornar isso?

^{Nota:
192.168.0.103 está faltando porque é o host local.

Answer 1

Aqui está uma técnica para manter o cabeçalho na parte superior: redirecionar o arquivo e, a partir do fluxo, consumir a primeira linha e, em seguida, dar o restante das linhas para classificar.

{ IFS= read -r header; echo "$header"; sort -V; } < /proc/net/arp
