Ubuntu – Merge several text files into one text file

Folder has several text files and I want to merge them to Merge.txt when adding new files or editing files. Nothing advanced only copy the text and commit.

This should be super easy, but I can’t find anyone who has a solution.

# This is a basic workflow to help you get started with Actions

name: CI

Controls when the workflow will run

on:

Triggers the workflow on push or pull request events but only for the "main" branch

push: branches: [ "main" ] 
pull_request: branches: [ "main" ]

Allows you to run this workflow manually from the Actions tab

workflow_dispatch:

A workflow run is made up of one or more jobs that can run sequentially or in parallel

jobs:

This workflow contains a single job called "build"

build: # The type of runner that the job will run on runs-on: ubuntu-latest

# Steps represent a sequence of tasks that will be executed as part of the job
steps:
  # Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it
  - uses: actions/checkout@v4

  # Runs a single command using the runners shell
  - name: Merge TXT Files
    run: |
       find . -type f -name '*.txt' | while read fname; do

    You can use something like this to merge multiple .txt files to a single Merge.txt file, if you want to commit that Merge.txt file then you can use other existing actions. I am going to show only the file merging example.

    name: Merge multiple text files into a single file

on:
  push:
    branches: [ "main" ]
  pull_request:
    branches: [ "main" ]
  workflow_dispatch:

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v4

      - name: Merge TXT Files
        run: |
          # Create and show list of files being processed
          echo "Files being processed:"
          find . -type f -name '*.txt' ! -name 'Merge.txt' -ls
          
          # Merge files and create Merge.txt
          find . -type f -name '*.txt' ! -name 'Merge.txt' -exec cat {} + > Merge.txt
          
          # Show the merged file was created
          echo -e "nMerge.txt has been created:"
          ls -l Merge.txt
          
          # Show the content of Merge.txt
          echo -e "nContent of Merge.txt:"
          cat Merge.txt

    Output:
