curl 和 jq 替换值中的子字符串

Question

使用 curl 我从 github api:

得到 json

curl https://api.github.com/repos/angular/angular/pulls?label=comp%3A+zones&state=closed&page=1&per_page=5

结果：

[
  {
    "url": "https://api.github.com/repos/angular/angular/pulls/33703",
    "id": 338899730,
    "node_id": "MDExOlB1bGxSZXF1ZXN0MzM4ODk5NzMw",
    "html_url": "https://github.com/angular/angular/pull/33703",
    "diff_url": "https://github.com/angular/angular/pull/33703.diff",
    "patch_url": "https://github.com/angular/angular/pull/33703.patch",
    "issue_url": "https://api.github.com/repos/angular/angular/issues/33703",
    "number": 33703,
    "state": "closed",
    "locked": false,
    "title": "add AOT mode default to version 9 upgrade doc",

      [...]

与 jq :

$ curl 'https://api.github.com/repos/angular/angular/pulls?label=comp%3A+zones&state=closed&page=1&per_page=2' | jq --raw-output '.[] | "\(.id) \(.title)"'

我可以很好地将其格式化为

338899730 add AOT mode default to version 9 upgrade doc
338868666 update jiali's info on collaborator page of angular.io

如何在输出前从标题值中删除 add 和 update？

Answer 1

使用sub，例如：

.[]
| "\(.id) \(.title|sub("^(add|update) *";""))"
