Git Basic Commands

After installing Git, you can also configure it - most importantly, you can set a username and email address that will be connected to all your code snapshots.

You can learn more about Git's configuration options here: https://docs.craft.do/editor/d/93958d6f-1340-6147-fc3c-1be83d5bfef9/FE067BAC-75E9-40A9-9280-5125A1823AB4/b/7DF294EA-9ABC-40FD-8DD5-E9527B89FF29#50E78A39-91C6-4063-87FA-104A42C4C8BE

git checkout <branch-name> # Move to new created branch 
git branch -D <branch-name> # Delete branch 
git branch # See all branches
git merge <name> # Merge branches
# Merge from feature branch to main branch 
git checkout main

GitHub actions basic

• In public repositories, you can use GitHub Actions for free. For private repositories, only a certain amount of monthly usage is available for free - extra usage on top must be paid.
• The exact quotas and payment details depend on your GitHub plan, a detailed summary can be found here: https://docs.github.com/en/billing/managing-billing-for-github-actions/about-billing-for-github-actions
• If you can't find an "Actions" tab in your GitHub repository, you can should enable them as described here: https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/enabling-features-for-your-repository/managing-github-actions-settings-for-a-repository

First Workflow

name: First Workflow
on: workflow_dispatch # manually trigger the workflow

jobs:
  first-job:
    runs-on: ubuntu-latest
    steps:
      - name: Print greeting 
        run: echo "Hello World"
      - name: Print goodbye
        run: echo "Done - bye"

If you need to run multiple shell commands (or multi-line commands), you can easily do so by adding the pipe symbol ( | ) as a value after the run: key.

Example:

...
run: |
    echo "First output"
    echo "Second output"
