Como transformar a saída lscpu para o formato JSON?

  • 772

Tive que lidar com o caso de precisar dos dados de lscpusaída no formato JSON, mas -Ja chave não é compatível.

Então criei um script de linha de comando simples que permite transformar a saída simples em JSON, que postarei aqui como resposta.

bash

    echo {$(lscpu | sed 's/  */ /g' | sed 's/: /:/g' | awk -F ':' '{print "\x22"$1"\x22: \x22"$2"\x22,"}') | sed 's/,$/}/'

    Dois sedremovem espaços extras, awkcriam aspas duplas ao redor dos campos e, por último, sedsubstituem a última vírgula por chave, delimitando a matriz criada pela primeira chave.

    registro do console:
