Example: To get json record having _id equal 611
cat my.json | jq -c '.[] | select( ._id | contains(611))'
Remember: if JSON value has no double quotes (eg. for numeric) to do not supply in filter i.e. in contains(611)

[Tokio][tokio] 是 Rust 的開發框架,用於開發非同步 I/O 程式(asynchronous I/O,一種事件驅動的作法,可實現比傳統同步 I/O 更好的延伸性、效能與資源利用)。可惜的是,Tokio 過於精密的抽象設計,招致難以學習的惡名。即使我讀完教程後,依然不認為自己充分內化這些抽象層,以便推斷實際發生的事情。
