I guess "rm -f .git/HEAD" before would "fix" it. -Peff

Makes one wonder if it really "works" if .git/HEAD was created by older version of Git or in a repository where prefer-symlink-refs is enabled, though ;-)

The code for "checkout --orphan" is in builtin/checkout.c[1]. But if you want to do roughly the same thing with other tools, you can do: git symbolic-ref HEAD refs/heads/new-branch If you don't even have symbolic-ref handy, you can do: echo "ref: refs/heads/new-branch" >.git/HEAD That's not generally recommended, since future versions of Git may change the ref storage format, but it would work with any current version of Git. -Peff [1] Try update_refs_for_switch(), especially: https://github.com/git/git/blob/61856ae69a2ceb241a90e47953e18f218e4d5f2f/builtin/checkout.c#L635 and https://github.com/git/git/blob/61856ae69a2ceb241a90e47953e18f218e4d5f2f/builtin/checkout.c#L695
Where is git checkout --orphan implemented at.
I would like to see the source code to git checkout --orphan so I can learn how it works and so I can manually do what it does by hand on making a new branch with no history in the refs folder. I can only do it on my iPhone as my laptop has no internet or way to do it there, and the program on my iPhone does not have the method implemented yet visually to do it, forcing manual creation of the orphan branch by hand in the end. If the public github had all the codes to all commands and subcommands like the one above it would be nice or well at least a file that explains the source file each command and subcommands are from so that way a person like me can use as a reference to make our own git gui that has 100% of command line git features.
