A fun thing to do with ram is actually open it up and take a peek. This command will show you all the string (plain text) values in ram

sudo dd if=/dev/mem | cat | strings

don't think the cat is needed... or the dd... strings /dev/mem should work fine.

cat is not needed.

strings /dev/mem | grep "llama"

This looks like it came from my site: http://www.nixtutor.com/linux/general-troubleshooting-in-linux/ But never the less awesome command. :)

The fact that my bios branding pops up in my ram 15 times vaugely irks me.... I wonder what would happen if I removed them? # sudo perl -pi.bk -e's/Phoenix//g' That sounds more entertaining than the shutdown command right now.

Is this really possible on linux to read /dev/mem from non privilegied user? In FreeBSD you can't read the file if you user doesn't belong to the kmem group: %head /dev/mem head: /dev/mem: Permission denied %ls -lh /dev/mem crw-r----- 1 root kmem 0, 32 Dec 5 18:39 /dev/mem

What do you think?

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
