Are you still in the computer shell, or in the ADB shell? Before typing in the cat command, you should type:

adb shell

and be sure you have a # sign for the prompt.

Try using this at the # prompt to remount the system as read/write:

su
mount -o remount,rw /system /system

It'll do that when using ADB in command prompt. When I was rooting my OV for the first time, it would do the same. Just continue what you were doing.
