How to change my local Git branch name to uppercase

Question

I created a branch from my master (origin) and called it TEST-101 (uppercase). I then worked on my branch and committed and pushed my changes up to origin. When I log in to Github, I can see I the branch I created.

I used git bash and checked out my local version of the branch, but I entered it in all lowercase: test-101. I then used Git Gui and committed my changes to the branch which was typed in lower case, and when I tried to push these changes it gave me an error:

POST git-receive-pack (390618 bytes)
remote: error: failed to lock refs/heads/test-101
Pushing to ht://example/example/example/example.git
To ht://example/example/example/example.git
! [remote rejected] test-101 -> test-101 (failed to lock)
error: failed to push some refs to 'http://example/example/example/example.git'

(Please note that I have changed some private info in the error.)

I have done some reading, and it appears that my local branch being in lowercase and the remote branch being in uppercase may be causing an issue?

Answer 1

The following solved the problem:

git branch -m test-101 tmp_branch
git branch -m tmp_branch TEST-101

Answer 2

You can do the following:

git branch -m test-101 tmp_branch
git checkout tmp_branch
git merge TEST-101 // make sure your data is up to date
git branch -D TEST-101
git branch -m tmp_branch TEST-101

-m option renames the branch, and -D option will delete the branch.
