How to save commit changes without editing when doing a merge in a script?

Question

I wonder how to add in my basic script some commands with nano, Ctrl-O, Enter, Ctrl-X, Enter. You can see what I want at the end of the script. It is after git merge, I just need to save commit changes (formality)

#!/bin/bash

## Set Local Rebase ##
git config pull.rebase true

## Update OpenWRT Scripts
./scripts/feeds update -a
./scripts/feeds install -a

## 5.4 kernel
git remote add wrt https://github.com/james/openwrt.git
git fetch james
git checkout -b wrt james/kernel5.4-qsdk10.0
git checkout master
git merge wrt
*ctrl o*
*enter*
*ctrl x*
*enter*
