Solved `less` bug

[bluray]

I run `zfs | less` and it enters less showing the end of the output (first picture) then already inside less when I press the up-arrow to see the top of the zfs command output it shows nothing (second picture). The same behavior happens in the ttyv system console btw. It's a problem with less, because I tested with other commands like `camcontrol | less` and it fails the same way. EDIT: It does work when I pipe dmesg to less though.

It's a problem between less and stderr:
Redirect stderr to stdout (sh/bash/zsh):

zfs 2>&1 | less

I'm still learning freebsd (*nix in general), thank you very much

It seems, the output of these commands are not to stdout, but to stderr.
