Jq：为每个对象收集 JSON 数据

Question

我发现我的标题不太清楚，但是我不知道如何更好地重写它，所以请随意编辑它！

期望的输出
这是一个包含两个对象的数组。我对这两个对象的genes_id 和pathways 感兴趣，并希望获得一个包含以下内容的制表符分隔文件：

eco:b0002   eco00260    Glycine, serine and threonine metabolism
eco:b0002   eco00261    Monobactam biosynthesis
eco:b0002   eco00270    Cysteine and methionine metabolism
eco:b0002   eco00300    Lysine biosynthesis
eco:b0002   eco01100    Metabolic pathways
eco:b0002   eco01110    Biosynthesis of secondary metabolites
eco:b0002   eco01120    Microbial metabolism in diverse environments
eco:b0002   eco01130    Biosynthesis of antibiotics
eco:b0002   eco01230    Biosynthesis of amino acids
eco:b0003   eco00260    Glycine, serine and threonine metabolism
eco:b0003   eco01100    Metabolic pathways
eco:b0003   eco01110    Biosynthesis of secondary metabolites
eco:b0003   eco01120    Microbial metabolism in diverse environments
eco:b0003   eco01230    Biosynthesis of amino acids

我发现了什么
我知道可以以如下格式提取数据：

eco:b0002: list of pathways and ids
eco:b0003: list of pathways and ids

但是，我想将路径传播到各个行，如上例所示。我找不到有关如何使用 jq 执行此操作的任何信息，因此怀疑这是否真的可行。因此，如果这是可能的，如何使用 Jq 来实现？

Answer 1

调用：jq -rf totsv.jq input.json

程序（totsv.jq）：

.[]
| .genes_id as $id
| .pathways
| to_entries[]
| [$id, .key, .value]
| @tsv

TSV 是一个不错的选择（jq 也是如此）！
