我只能提取版本
$ cat automationConfig | jq '.processes[] .version'
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
现在我想使用 shell 工具 jq 将数字“3.0.7”替换为“3.0.6”。
我正在关注此 docs.mongodb.com，但希望降级（而不是升级）。
搜索具有您要更新的版本的进程，然后更新它们。
(.processes[] | select(.version == "3.0.7")).version = "3.0.6"
现在您已经提取了所需的值，接下来只需为它们分配一个新值即可。
$ cat automationConfig | jq '.processes[].version = "3.0.6"'
此处从 JSON 输出中提取。 JSON 文档 automationConfig 是 MongoDB Ops Manager，一个用于管理 mongod.
$ cat automationConfig | jq '.processes[]'

我只能提取版本
$ cat automationConfig | jq '.processes[] .version'
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
"3.0.7"
现在我想使用 shell 工具 jq 将数字“3.0.7”替换为“3.0.6”。
我正在关注此 docs.mongodb.com，但希望降级（而不是升级）。
搜索具有您要更新的版本的进程，然后更新它们。
(.processes[] | select(.version == "3.0.7")).version = "3.0.6"
现在您已经提取了所需的值，接下来只需为它们分配一个新值即可。
$ cat automationConfig | jq '.processes[].version = "3.0.6"'
