Or any other log files/output? I'm open to any solution, but what I would like...
...is something where I can just click on a word or select some text and say "filter that out"
Something that colors different log levels differently, preferably automatically.
Something that can parse the "columns" and give me a nice quick list of values, like different unit names to filter out/solely include.
Something that lets me choose a time and go there. Something that lets me select only a specific timeframe of logs.
I know this can probably be done by going in/out of journalctl, recalling the last command and adding specific filter options... but it just feels slow. It's so many keypresses when I could just right click on the word and -> "Filter out/Search for" or something.
You can't change people. They have to want it themselves. If she's not looking for any help, there's nothing you can do.
The only thing that might happen if you're not a very actually good friend with them, is they might dial it back in your presence to not be annoyed by you about it.
Complaining does not constitute "wanting help". Most people complain just because it makes them feel better in the moment.
