git-learn

Let us learn how to use git command and GitHub

Let us improve efficiency.

Let us cooperate!

Reset

use the following command to go back to an old commit. get reset --hard <commit>

Reset the current branch to the state of the commit specified by the n-th previous commit in the commit history, discarding all changes made after that commit and moving the HEAD pointer to that commit. get reset --hard Head@{n}

Branch

Create branch with git branch new and go to the branch via git checkout new

Merge

merge new to main by git merge new

Action

create .github/workflows/*.yml

Example:

name: MyAction

on: [push, pull_request]

jobs:
  build:

    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v3

      - name: Print OK
        if: contains(github.event.head_commit.message, 'print')
        run: echo "OK!"
