hello-world

This is my first repository. This is the text associated with my first branch. I wanted to change the capitaliation. Here I wanted to add a line locally via the command line.

Here I am testing how branching works. Adding my text here. Wow! And now I am testing it again with a new commit. Will this new line be added? How will it appear in GitHub?

To change the default branch, thanks to rhymu8354:

git clone <repository_URL>
cd <repository_dir>
git branch -m master main
git push -u origin main
# Change the default branch in repository page at GitHub.com, etc.
git push origin --delete master
git remote set-head origin -a

This is wonderful. Now, I'm making changes so I can test pushing a commit with SSH authentication. Thanks to Martin V. Loewis I was able to clone the repository with:

ssh-agent bash -c 'ssh-add /gs/gsfs0/users/gstefan/pw/workflows/tmp_id; git clone [email protected]:stefangary/hello-world.git'

and now I'm going to do:

git add .
git commit
ssh-agent bash -c 'ssh-add /gs/gsfs0/users/gstefan/pw/workflows/tmp_id; git push origin'

Great! That worked. Now I'm going to test pushing another commit on a different machine (via PAT) and then pulling that update to yet another machine (via SSH). So, first edit, then do the usual

# On a different computer
git add .
git commit
git push origin

And then, on the first computer where I have the repo already and tried SSH auth:

# Should not work due to [this issue](https://stackoverflow.com/questions/52379234/git-gnutls-handshake-failed-error-in-the-pull-function)
git pull

# Should work
ssh-agent bash -c 'ssh-add /gs/gsfs0/users/gstefan/pw/workflows/tmp_id; git pull'

Confirmed it does work! Also confirmed that the key is not stored somewhere with ssh-add - the ssh-agent usage of the key is a one-time. Also confirmed that ssh-agent prompts for key password before using it and if key password is wrong, everything stops. So commit and push this last confirmation back to GH:

git add .
git commit
ssh-agent bash -c 'ssh-add /gs/gsfs0/users/gstefan/pw/workflows/tmp_id; git push origin'
