有一个来自成像会话的日志文件,我需要从中提取位于某个触发器之前的多行参数。一旦找到触发器,我就想打印收集的数据并重新开始。
使用 grep,我提取了触发器之前的行。触发器应为“自动对焦完成”。这是我得到的结果,并希望进一步将其输入到 awk 中进行参数提取和打印。

我想要捕捉:
- “移动调焦器到位置”后面的数字
- “平均 HFR:”后面的数字
- “已探测到的星星”后面的数字
一旦我遇到“自动对焦完成”,我想打印在 .log 和 |INFO 之间的行部分中编码的时间和日期,然后是位置 hfr 和星星
我尝试了部分代码,但未能打印出 hfr 和日期

更新以解决 Ed Morton 的回答
awk 脚本仅与前面的 grep 配合使用。似乎模式的某些部分只与 grep 前面的文件名挂钩。没有 grep 则不起作用。不过这是完全可以接受的,我会将其标记为选定的答案。
这有效:

这不起作用:
cat 20240831-195957-3.1.1.9001.10824-*.log | awk -f AF_stats.awk
使用 GNU awk 将第三个参数设置为
match()
:我希望它能在您的原始输入文件上运行而无需您运行
grep
它,但如果没有看到它,那只是一个猜测。
