Need script to change a line in file....

Hello all,

I have a line of code in a file that I need to change in the /etc/sysconfig/kdump file
presently the line reads:

Code:
KDUMP_COMMANDLINE_APPEND="irqpoll nr_cpus=1 reset_devices cgroup_disable=memory mce=off"

what I need to do is put a comment out the 1st line and repeat it, and change nr_cpus=1 to maxcpus=1.
I am looking for the final result to look like:

Code:
# KDUMP_COMMANDLINE_APPEND="irqpoll nr_cpus=1 reset_devices cgroup_disable=memory mce=off"
KDUMP_COMMANDLINE_APPEND="irqpoll maxcpus=1 reset_devices cgroup_disable=memory mce=off"

thanks,

really appreciate any assistance.
