如何将从Osquery触发的SQL查询的输出保存到文件

我已经在机器上安装了Osquery实用程序。当我启动SQL命令时,它将输出输出到STDOUT。有什么办法可以将输出重定向到文件吗?

$ sudo osqueryi

我希望将此输出保存在文件中。我检查了Osquery的官方文档。但是解决这个特定问题并没有帮助。 https://osquery.readthedocs.io/en/stable/introduction/sql/#sql-as-understood-by-osquery

osqueryi通常用于交互使用。当保存到文件或将osquery包含在数据管道中时,人们通常使用osqueryd配置计划的查询。

https://osquery.readthedocs.io/en/stable/deployment/configuration/有一些非常简单的配置示例。

您还可以在命令行上指定查询,然后在外壳程序中执行任何操作。

您可以使用Shell的重定向功能:

$ osqueryi --json 'select * from osquery_info' > res.json
$ cat res.json
[
  {"build_distro":"10.12","build_platform":"darwin","config_hash":"e7c68185a7252c23585d53d04ecefb77b3ebf99c","config_valid":"1","extensions":"inactive","instance_id":"38201952-9a75-41dc-b2f8-188c2119cda1","pid":"26255","start_time":"1552676034","uuid":"4740D59F-699E-5B29-960B-979AAF9BBEEB","version":"3.3.0","watcher":"-1"}
]

请注意,在此示例中,我们使用JSON输出。还有其他选项:--csv--line--list

如seph在https://stackoverflow.com/a/55164199/491710中所述,在osqueryd中安排查询并将结果推送到日志记录管道是常见的用例。
