Description

Situation:

In file /etc/sysctl.conf:

node 1 has: kernel.shmmax = 1234
node 2 has: kernel.shmmax = 4321
node 3 has: kernel.shmmax = 2143

Actually the value could be anything. And I don't (want to) know what is is.

Now I want to accomplish this:

node 1 has: kernel.shmmax = 5678
node 2 has: kernel.shmmax = 5678
node 3 has: kernel.shmmax = 5678

What I need here is one simple regex that matches:

All lines in sysctl.conf, which start with "kernel.shmmax", followed by a space, followed by an = sign, followed by a space, followed by a number I don't know.

Please provide documentation on how to do this.
