Zdrojak programu dmesg - kde?

**Rainbow** · 27.09.2003, 15:08

Kde zozeniem zdrojak programu dmesg? Cez Google som nic poriadne nenasiel - vsade je len verzia pre Amigu, ktora je sucastou zdrojakov jadra... Chcem z toho zistit, ako sa da citat z toho chyboveho vystupu jadra.

Este mam jednu otazku - nefunguje mi /proc/kmsg. Ked spustim "cat /proc/kmsg", tak to nic nerobi - nic nevypise, len caka (na co

). Musi byt nieco spustene, aby to fungovalo?
