lscpu出力をJSON形式に変換するには？

lscpuデータをJSON形式で出力する必要がありますが、-Jキーがサポートしていない状況を処理する必要がありました。

そこで、一般的な出力をJSONに変換できる簡単なコマンドラインスクリプトを作成し、ここに答えとして投稿します。

答え1

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

2番目はsed余分なスペースを削除し、awkフィールドの周りに二重引用符を作成し、最後のsedカンマを最初の中括弧で生成された配列を囲む中括弧で置き換えます。
