Git

List existing remotes

git remote -v
or
git remote show origin

Set remote’s URL

git remote add origin https://github.com/USERNAME/REPOSITORY.git

Change remote’s URL

git remote set-url origin https://github.com/USERNAME/REPOSITORY.git

Generate changelog since last tag

git log $(git describe --tags --abbrev=0)..HEAD --pretty=format:"%s"
git log $(git describe --tags --abbrev=0)..HEAD --pretty=format:"* %s by @%an in https://github.com/my-org/my-repo/commit/%H"

Get last tag (semver speaking)

git tag -l --sort=-version:refname | head -1

Rebase the first 2 commits

git rebase -i --root

Reset the last commit and keep changes

git reset HEAD~1

Apply a change to a previous commit which is not last commit

git rebase -i HEAD~{number of commits to go back}
 => set "pick" to "edit" at the commit you want to change
 => apply the changes to your files
git add .
git commit --amend --no-edit
git rebase --continue

Force to reset a branch as a remote one (here origin/master)

git reset --hard origin/master
