Hi @chris-c-thomas ,

Github hosted runner will be released after workflow completed, thus it will not store the generated files, you need to push the files to repo.

Step1: put the generated files into dir ‘output’.

Step2: push the output folder to your repo.

You can check my sample code below, my repo here.

name: commitfiles
on: [push]
jobs:

job1:

runs-on: [ubuntu-latest]

steps:

- name: checkout

uses: actions/checkout@v2

- name: Modify value # Tried to modify the files based on existing testfile.txt

run: |

echo 'Add value2' >> testfile.txt

- name: move to dir # Move the generated files into output folder

run: |

mkdir -p output

yes| cp -rf testfile.txt ./output/

- name: Commit files # commit the output folder

run: |

git config --local user.email "test@github.com"

git config --local user.name "GitHub Action test"

git add ./output

git commit -m "Add changes"

- name: Push changes # push the output folder to your repo

uses: ad-m/github-push-action@master

with:

branch: B77 #ignore if your branch is master

github_token: ${{ secrets.GITHUB_TOKEN }}

force: true

Hope it helps.
