Computer Tips - I know I need to reboot my box when the kernel is updated for it to

Q.  I know I need to reboot my box when the kernel is updated for it to
come into effect but I have automatic update running so... I can I tell
if I need to reboot my machine?

A.  Compare the currently running kernel version with those installed.

To see what's currently running do:

uname -r

And you might get:

2.6.25.9-76.fc9.i686

To see what's installed (on RedHat/Fedora/CentOS) do:

rpm -q kernel

And you might get:

kernel-2.6.25.6-55.fc9.i686
kernel-2.6.25.9-76.fc9.i686

If the version you are running is the biggest one installed then you don't
need to reboot.
