如何僅顯示“guix 搜尋”的結果名稱

例如，當我跑步時，guix search openjdk我會得到一長串資訊，其中大部分我都不感興趣：

name: openjdk
version: 9.181
outputs: out jdk doc
systems: x86_64-linux i686-linux

...

有沒有辦法只顯示每個包的名稱和版本？

是的，使用小實用程序recsel（來自recutils包）：

$ guix search openjdk | recsel -p name,version
name: openjdk
version: 9.181

name: openjdk
version: 14.0
