nu 命令

常用示例

说明

nu is Nushell, a cross-platform shell that treats every command's output as structured data (tables, records, lists) flowing through a pipeline. Built-ins parse common formats (JSON, YAML, TOML, CSV, SQLite, ODS, XLSX, XML, NDJSON) into the same table type, so commands such as `where`, `sort-by`, `select`, `group-by`, and `histogram` work uniformly across data sources. Pipelines pass typed values rather than byte streams, which makes data wrangling expressive but means traditional Unix pipes mixing arbitrary byte streams behave differently — wrap external commands with `^cmd` to get raw stdout, or use `into binary` / `into string` for explicit conversions.
