Assistance with my one line command to find all inactive kernels

Hello Forum,

I'm using the following command to find all inactive kernels installed on my RHEL server:

Code:
$ rpm -qa | grep '^kernel-[0-9]' |grep -vE `uname -r`

but the result is in two lines:

kernel-3.10.0-1062.1.1.el7.x86_64
kernel-3.10.0-1062.el7.x86_64

Is there a one line command I can issue to find all inactive kernels like I'm using but put all the kernels found on one line separated by a semi-colon (I use CSV for my output file so I don't want them separated by commas).

Thank you.
