+1 +1 +1 ... Yup. uname -a will give you running kernel info and your package manager will undoubtedly have a query command permitting you to find installed packages. As mentioned - kernel headers and docs aren't actually "running" - the kernel is. And yes, you may have several kernels installed and available to boot on your system - to be chosen at boot time.

Cheers :-)

I would look at it this way (on a RHEL/Centos/... distro):

Code:

# running kernel : also usually matches the 1st entry in /boot/grub/grub.conf
uname -a

# Other installed & avail kernels : see also other entries in /boot/grub/grub.conf
rpm -qa| grep -i kernel

NB: I don't have v7, so the above may not be true for v7.
