Log File Viewer for the Terminal

Oh yeah! lnav is famous. I remember using it like a decade ago to monitor an array of web servers while at GoDaddy; good ol' times.

First commit is from Sep 13, 2009: https://github.com/tstack/lnav/commit/b4ec432515e95e86ec9d71... . Woah! we’re old.

This is what the UX looked like back in the day: https://github.com/tstack/lnav/commit/bce2caa654160518ec11f6...

This looks great.

I've been using klogg and if you're more into GUI's then I think it's the best there is. It opens and searches in log files of many gigabytes with easy. It's a simple and clean multiplatform QT app.

This is almost the thing I want and need. What I need is some sort of TUI grafana - Json log splitter/organizer/finder

I wish I had found this earlier. Nothing like looking at thousands of EV charger logs all day to mak you appreciate something like this.

Really appreciate this way to demo it quickly, very nice!

I tried lnav about 7-8 years ago and as a terminal junkie I really liked the features.

The only breaking thing was a huge (almost bloated) memory consumption. At that time lnav basically just kept everything in memory. Does anyone did that change?

Looks very useful, will give it a go.

This resonates with my use of grep+less: https://github.com/tstack/lnav?tab=readme-ov-file#why-not-ju...

Must have tool!

I was looking for something like this, Appreciate it!

This looks genuinely useful.

I'm a little disappointed that it's not written in Rust.

It's a nice tool but I really wish the configuration wasn't done in json and loaded from $XDG_CONFIG_HOME.

very nice, definitely will use it

Super useful tool but need to be aware that this is reading potentially untrusted input (e.g. in the case of http request logs) and written in c++, so a possible attack vector. I use lnav where I trust the logs, but do wish a safe implementation existed.
