[SOLVED] lesspipe.sh breaks forward mode

Hello.

For few years I struggled with `less` because it lacks the most killer feature that works on the Debian servers I operate.

The Debian uses another script, it's here https://sources.debian.org/src/less/458 … /lesspipe/. With this script forward mode works pretty well. It jumps directly to the EOF and shows the lines appearing in the file. Log for example.

But the script that is used in archlinux https://github.com/archlinux/svntogit-c … pipe/trunk loads the full file (because it definitely shows every line) and then stops to follow the new data.

The difference between plain less and lesspipe.sh is visible in the screencast https://asciinema.org/a/396774

What is the proper way to solve it now? The lesspipe is quite a necessary thing to have a way of reading the compressed logs. But it screws the crucial part of less.

Re: [SOLVED] lesspipe.sh breaks forward mode

This is a functionality of less that should be irrelevant towards the used wrapper script for other formats, press Shift+F to enable less' follow mode

Oh wait I misread that, sounds weird

Maybe, it's better to report a bug directly to https://bugs.archlinux.org/ ?

Re: [SOLVED] lesspipe.sh breaks forward mode

Hey seth, thank you very much for directing me into the right place. I have misinterpreted the content of https://github.com/archlinux/svntogit-c … pipe/trunk and thought, that lesspipe.sh is unmodified for 12 years w/o taking a look into PKGBUILD source.

Re: [SOLVED] lesspipe.sh breaks forward mode

So, I'll put the solution here too. `less` won't respect LESSOPEN when `-L` argument is passed.
