Re: [shell-script-pt] Como iterar um array recursivo sem redundância?

[Vilmar Catafesta]

Olá Arkanon,

No caso do código abaixo, está listando TODOS os pacotes antigos
    $ sort -V pacotes.txt | rev | tr - '\t' | uniq -f3 | tr '\t' - | rev *# versões mais antigas

Necessário, no meu caso, listar somente os pacote antigos que tenham versão
mais nova :)

Dando trabalho para ti, rsrs

Saudações

Muda pouco :)
