Hi, all:
I noticed something weird with my git command. In my local environment I seem to have a branch named `-D`:
And I don’t remember how I was able to create a branch like that. I tried to do git branch -D/-d this branch but seems not working. I’m assuming the branch infos were kept in .git folder so my question is if there’s anyway I could remove this invalid branch from that folder? My git version is 2.24.0. Thanks for any help in advance.

You can delete oddly-named branches by passing the end-of-options marker
to 'git branch', like so:
$ git branch -D --end-of-options -D
(In fact, '--end-of-options' isn't strictly necessary here, and using
'--' as in 'git branch -D -- -D' will work as well).
If you do find a reproducible way to create branches named '-D' or
similar, please do let us know, as these are not intended to be valid
branch names in general.
Thanks,
Taylor

$ git update-ref refs/heads/-D master
$ git branch |head -n1
-D

I was assuming that Jude had gotten the ref to appear by using 'git
branch' alone, i.e., without the help of 'git update-ref' or 'cp
.git/refs/heads/{master,-D}'.
Thanks,
Taylor

On a somewhat related note, while trying whether I could
"inadvertently" create such a branch with gitk I stumbled upon this
bit of weirdness:
$ git rev-parse v2.24.0^{commit}
da72936f544fec5a335e66432610e4cef4430991
$ git branch da72936f544fec5a335e66432610e4cef4430991 v2.24.0
$ gitk -1 v2.24.0
(While starting up gitk might show a popup warning about the branch
with 40 hexdigit name, close it.)
So now gitk displays a commit with the v2.24.0 tag and the da7293...
branch pointing to it. Right click on the commit's subject line,
select "Create new branch" from the context menu. Enter "-D" as the
name of the new branch, and click Create. Now gitk displays a "-D"
branch pointing to the same commit as well, but it's only a display
thing, as it did not actually create that branch, because it
carelessly run the 'git branch -D da7293...' command... After
refreshing with F5 it won't display the da7293... and "-D" branches.
