18.000
0.00000
Eu tenho outro problema grep / awk / sed dentro do código HTML anexado abaixo.
Dado é um arquivo HTML simples com tabela dentro. O HTML é gerado por um medidor inteligente (medidor de energia doméstico). Dentro da tabela html, são apresentados 2 valores que são importantes para mim: Pplus e Pminus. Estes são o poder real do GRID e a energia real vinda da minha planta solar.
Eu gostaria de pegar esses dois valores separadamente como "estável / seguro" para ficar menos propenso a erros. Meu entendimento é que a estrutura do html nunca muda. Como ponto de partida para encontrar os valores, 18.000
significa 18W de energia atual da rede de energia e 0.00000
significa 0W atualmente produzido a partir de minha usina solar (sua noite).
Para mim, é quase impossível encontrar alguma estrutura que possa ajudar a conquistar a posição certa, eu realmente aprecio sua visão de especialista aqui e se é possível fazer isso funcionar.

Eu tentei os comandos mencionados acima, mas eles não parecem funcionar.
O comentário abaixo, sobre python, como isso funcionaria, alguém pode me ajudar? Eu não tenho nenhuma preferência, mas claro que prefiro a melhor solução que parece estado da arte em todas as direções (velocidade, eficiência, ....)
O HTML postado não muda, apenas os valores do curso são atualizados a cada 10 segundos.
> awk '/ID="idButtonTd"/ {printline=1; next;};
printline==1 && /^[0-9]+\.[0-9]+$/ { print $0; }; { printline=0; }' file
18.000
0.00000
Se a estrutura html for de fato constante, o seguinte deverá funcionar:
totalValues=$(grep -A1 "idButtonTd" yourfile | grep -v "idButtonTd" | grep -v "\-\-" | grep "^[0-9][0-9]*")
Pplus=$(echo $totalValues | awk '{ print $1 }')
Pminus=$(echo $totalValues | awk '{ print $2 }')
echo "Pplus = $Pplus"
echo "Pminus = $Pminus"
