Git Brain

Common Tasks

checkout a branch

git checkout branchname

force git to forget about a file

git rm --cached .gitbook/assets/Jenkins.png

to restore a file to what it was before current working changes

git restore file

to abort a rebase operation

git rebase --abort

show the remote url

git remote show origin

Fancy repo stuff

If you have two local copies of a repo, you can add one as a remote for the other, to push branches between them.

First, add the second dir as a remote for the first, giving it a name (josh_fork in this case).

git remote add josh_fork ../hiero-consensus-node-personal

Then push to that local remote with -u.

git push -u josh_fork

GitHub Actions

setup SCP in an action

• create ssh keypair on the server as a specific user used just for uploading

• copy the private key to a github secret

• append the public key to the .ssh/authorized_keys file

• make a github action that uploads the artifacts using this scp action

The action looks like this:

name: Publish Brain

on:
  push:
    branches: [main]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Use Node.js ${{ matrix.node-version }}
        uses: actions/setup-node@v3
      - run: npm ci
      - run: npm run build-brain
      - name: copy file with ssh password
        uses: appleboy/scp-action@v0.1.7
        with:
          host: myserver.com
          username: deployuser
          port: 22
          key: ${{secrets.DEPLOYUSER_PRIVATE_KEY}}
          source: "*.html"
          target: remote_path
