This one?
/bin/dd bs 1 if /proc/kmsg of /var/run/klogd/kmsg

> Can anyone please explain what purpose this dd is running?

It copies kernel messages from to /var/run/klogd/kmsg to avoid
needing to run klogd as root (which is necessary to read /proc/kmsg)

Same here on my Kubuntu system.
It's running as root so must be something the system uses.
No clue what for.

the running process is:
/bin/dd bs 1 if /proc/kmsg of /var/run/klogd/kmsg

It's for kernel messages [watch the wrap]:


5.2.15. /proc/kmsg
This file is used to hold messages generated by the kernel. These
messages are then picked up by other programs, such as /sbin/klogd or
/bin/dmesg.

Thank you. Makes perfect sense. Can't wait until my Ubuntu book arrives so
I can research some of this.

Don't wait! Use what you already have (it's free).

john@ubuntu6.06:~$ ps ax | grep "dd "

3925 ? Ss 0:00 /bin/dd bs 1 if /proc/kmsg of /var/run/klogd/kmsg

man dd

You will learn what dd, bs, if, and of all mean.

kmsg? Kernel Message.

Why buy books, written by who-knows-who? Your included documentation,
and online resources, are current, searchable, copyable, ....

Let the trees filter our air, and leave the paper products for the

The EULA sounds like it was written by a team of lawyers who want to tell me what I can't do. The GPL sounds like it was written by a human being, who wants me to know what I can do.
