Markdown General Infos

Add a pc to github

  • ssh-keygen -t ed25519 -C "[email protected]"
  • ssh-add ~/.ssh/id_ed25519
  • vim ~/.ssh/id_ed25519.pub and paste it in github page settings
  • eval ssh-agent -s
  • ssh-add ~/.ssh/id_rsa_key

Tips

  1. To reference a commit in a issues comment, simply write its SHA-hash, and it'll automatically get turned into a link
  2. Want to save an empty directory? use the .gitkeep file trick!
  3. link/anchor to chapther/heading example
  4. git config --global credential.helper 'cache --timeout=99999999'

"We found a potential security vulnerability in one of your dependencies" message

Solution: just click on the Github's alert for information, usually you just need to update dependencies.

"Something went really wrong and we can’t process that picture."

While switching profile's picture.

Solution: switched browser and it worked.

Hide forever a file

Example: remove README.md from history and everywhere:

git filter-branch --force --index-filter \
  'git rm --cached --ignore-unmatch README.md' \
  --prune-empty --tag-name-filter cat -- --all

and

git push --all --force

Updated version 2022, removing __pycache__ folder

git filter-branch --force --index-filter  'git rm --cached --ignore-unmatch __pycache__'  --prune-empty --tag-name-filter cat -- --all
git push --all --force

Hide forever history of an entire branch

git checkout --orphan tmp-master # create a temporary branch
git add -A  # Add all files and commit them
git commit -m 'Add files'
git branch -D master # Deletes the master branch
git branch -m master # Rename the current branch to master
git push -f origin master # Force push master branch to Git server

Change commit email

git config --global user.email "[email protected]"

Check it:

git config user.email
