Create an orphan branch in a repo.

git_create_orphan.sh

cd repository
git checkout --orphan orphan_name
git rm -rf .
rm '.gitignore'
echo "#Title of Readme" > README.md
git add README.md
git commit -a -m "Initial Commit"
git push origin orphan_name

git reset --hard also removes everything to its initial state

git reset --hard also removes everything to its initial state

according to this answer on StackOverflow, git reset --hard cannot be helpful in this specific case.

Interesting, it's worked for me. For example:

Rob@Robtimus MINGW64 /d/Code/Java/github/connect-sdk-java/connect-sdk-java-spring-boot-starter (master)
$ git status
On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean

Rob@Robtimus MINGW64 /d/Code/Java/github/connect-sdk-java/connect-sdk-java-spring-boot-starter (master)
$ ls | wc -l
5

Rob@Robtimus MINGW64 /d/Code/Java/github/connect-sdk-java/connect-sdk-java-spring-boot-starter (master)
$ git checkout --orphan orphan-branch
Switched to a new branch 'orphan-branch'

Rob@Robtimus MINGW64 /d/Code/Java/github/connect-sdk-java/connect-sdk-java-spring-boot-starter (orphan-branch)
$ ls | wc -l
5

Rob@Robtimus MINGW64 /d/Code/Java/github/connect-sdk-java/connect-sdk-java-spring-boot-starter (orphan-branch)
$ git reset --hard

Rob@Robtimus MINGW64 /d/Code/Java/github/connect-sdk-java/connect-sdk-java-spring-boot-starter (orphan-branch)
$ ls | wc -l
1

Rob@Robtimus MINGW64 /d/Code/Java/github/connect-sdk-java/connect-sdk-java-spring-boot-starter (orphan-branch)
$ git status
On branch orphan-branch

No commits yet

Untracked files:
  (use "git add <file>..." to include in what will be committed)
        .classpath
        .project
        .settings/
        target/

nothing added to commit but untracked files present (use "git add" to track)

After the checkout, I omitted the git status because it showed every file being marked as a new file. Maybe that's why it didn't work on SO, because files were not part of the index.

Note that using git switch --orphan <branch name> automatically removes ALL files from the working tree.

Commenting on KartikSoneji (Jul 15) above: git: 'switch' is not a git command. See 'git --help'.

@anfxanfx
git switch was introduced in git 2.23, you might need to update your git client.
https://git-scm.com/docs/git-switch

For those who don't have access to a bleeding-edge version of git, I have a simple work-around: make an empty commit when the repo is new, tag it, and then use that as the base for any orphan branches.

git init
git commit --allow-empty
git tag empty

then git checkout --orphan new_branch empty.

As a bonus, you can now use git rebase -i empty, to amend or remove what would otherwise have been the "initial" commit.

@KartikSoneji the documentation still (as of 2.29.0) says:

THIS COMMAND IS EXPERIMENTAL. THE BEHAVIOR MAY CHANGE.

On git 2.23, all I needed was:

git switch --orphan <branch_name>
git commit --allow-empty -m "<commit_msg>"
git push origin <branch_name>

you're looking for "checkedout", not "checkout'ed" 👍

@SeanHorner see gist:7df6c8a5…

(I note that checkout is a git verb, so in this context it's not so unreasonable to conjugate it as checkouts and checkouted - just as long as nobody says those out loud.)

Ah, didn't think about it in that context, was using my linguist brain, not coding brain xD. Very interesting (and thorough) discussion in the linked gist 👍

Note that using git switch --orphan <branch name> automatically removes ALL files from the working tree.

Note that whatever is ignored by .gitignore won't be removed.

Note that git switch --orphan <branch name> automatically removes ALL tracked files from the working tree (as it should, since we don't want files from other branches — it's an orphan branch). It will not remove

• untracked files
• modified (not yet committed) tracked files (because it refuses to proceed in this scenario)

This is independent of .gitignore. However, there are many other ways to exclude files (e.g. .git/info/exclude, git update-index --skip-worktree etc). If you use any of those, possibly together and along .gitignore, you probably have bigger things to worry about.
