How do I view var log Kern logs?
Linux logs can be viewed with the command cd/var/log, then by typing the command ls to see the logs stored under this directory. One of the most important logs to view is the syslog, which logs everything but auth-related messages.
Where can I see syslog logs?
Some of the most important Linux system logs include: /var/log/syslog and /var/log/messages store all global system activity data, including startup messages. Debian-based systems like Ubuntu store this in /var/log/syslog , while Red Hat-based systems like RHEL or CentOS use /var/log/messages . /var/log/auth.
Is it safe to empty var log?
So the short answer is no, don’t delete everything in /var/log — it breaks the contract users with sufficient privileges to do such things have with the applications that run on their system, and will cause some noise, some silent failure to log, and some all-out breakage.
What’s the difference between kern.log and / var / log / syslog?
One just sets up a dedicated syslog server which collects all the individual device logs over the network. Syslog can also save logs to databases, and other clients. According to my /etc/syslog.conf, default /var/log/kern.log captures only the kernel’s messages of any loglevel; i.e. the output of dmesg.
Is there a way to delete Kern log file?
As you need root permissions to do that, you won’t have an option in the GUI to delete that file. Each time you boot, log files will be created and rotated again, so you should probably watch for the next kern.log.* file sizes.

Where is kern.log file in BusyBox tools?
There is no kern.log in that log folder, though. All that’s in there is: messages, resolv.conf, sshd, and then folders: dbus, subsys. I’d like to inspect, after reboot, the kern.log (or whatever equivalent file) to see what happened before the system froze when using a certain driver. Can I do this with the BusyBox tools?
How big is kern.log file in Ubuntu?
Tracing back, I find that it is the syslogs, especially the kern.log (s) that are eating up my 1TB disk.
