safest way to continuously monitor dmesg in a terminal [solved]

graysky · 2012-07-29 09:12:58

Googling suggests that the following is a safe method to monitor dmesg in a shell. I'd prefer not to use sudo. Any suggestions? Is it safe to chmod 644 /var/log/kernel.log or is that a bad idea?

$ sudo watch /proc/kmsg

or

sudo tail -f /var/log/kernel.log

The group of most log files is 'log' and group has read access, so you could add yourself to the log group (but I don't know if it's used for other things/if this is a good idea).

Use the log group, it's perfectly safe.

With linux 3.5 and util-linux 2.22, you'll be able to dmesg --follow.

Good to know, Dave. Thank you. Just waiting for CK to port ck1 from 3.4 to 3.5
