Linux Tutorial: The best way to Present Realtime dmesg Output in Linux

Final Replace: Mar 25, 2023

There are a lot of occasions in Linux you wish to watch your dmesg output, particularly when working with {hardware} to see what’s happening.

There’s really a very easy to method to do that, merely open one other terminal and sort:

tail -f /var/log/messages

It will present you the final messages posted in realtime. This might go for any log you need really, and works nice.

Additionally some distrosl have “tailf” which does the identical factor.

Additionally you may pipe your kernel output to a different terminal. Open /and so forth/syslog.conf and add the next line:

kern.*          /dev/tty10

This lets you change to that terminal to see the kernel output.

I hope this helps!
