使用jq在shell中过滤JSON列表 [英] Filtering JSON list in shell using jq

问题描述

输入:

{ "names" : ["name1","name2","name3","pat_name4"] }

所需的输出:

{ "names" : ["name1","name2","name3"] }

当前我通过运行命令所拥有的内容，以过滤出以 pat _

Currently what i have by running command, to filter out all names starting with pat_

cat file | jq .names | grep -Ev '^(pat_)'

这是

["name1","name2","name3"]

想知道是否可以对 jq 命令进行一些更改以获取所需的格式.

Was wondering if there is some alteration to the jq command that could be done to get in the format needed.

推荐答案

根据您的输入，调用:

$ jq -c '.names |= map(select(test("^pat_")|not))' 

产生:

{"names":["name1","name2","name3"]}
