Git
git - The stupid content tracker. Git is a stupid content tracker because it has no idea what's inside those blobs, and it doesn't try to store fine grained information like "lines 345-350 added, lines 502-508 removed" or anything like that.

How to clone github repository to your local terminal
$ git clone https://github.com/ardikas/shell-scripts
How to set up your terminal with remote access to your Github repo
You may see this when you try to commit:
$ git commit *** Please tell me who you are. Run git config --global user.email "you@example.com" git config --global user.name "Your Name" to set your account's default identity. Omit --global to set the identity only in this repository. fatal: empty ident name (for <ardika@DESKTOP-TOREEKS.localdomain>) not allowed
Do:
git config --global user.email "myemail@gmail.com" git config --global user.name "ardikas"
Another way to init Github repo:
git init git config user.name "someone" git config user.email "someone@someplace.com"
How to add SSH key and push using SSH
If you do git push and get this error, that is because password authentication was deprecated:
$ git push Username for 'https://github.com': ardikas Password for 'https://ardikas@github.com': remote: Support for password authentication was removed on August 13, 2021. remote: Please see https://docs.github.com/en/get-started/getting-started-with-git/about-remote-repositories#cloning-with-https-urls for information on currently recommended modes of authentication. fatal: Authentication failed for 'https://github.com/ardikas/python-scripts/'
Instead, my preferred way is to use SSH keys.
Follow these steps to generate an SSH key, add it to your Git Hub, and authenticate:
- https://docs.github.com/en/get-started/getting-started-with-git/about-remote-repositories#cloning-with-ssh-urls
- https://docs.github.com/en/authentication/connecting-to-github-with-ssh/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent#generating-a-new-ssh-key
- https://docs.github.com/en/authentication/connecting-to-github-with-ssh/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent#adding-your-ssh-key-to-the-ssh-agent
Then test the SSH key:
$ eval "$(ssh-agent -s)" $ ssh-add ~/.ssh/<githubkey> $ ssh -T git@github.com Hi ardikas! You've successfully authenticated, but GitHub does not provide shell access.
Change directory into the local clone of your repository (if you're not already there) and run:
$ git remote set-url origin git@github.com:ardikas/python-scripts.git
Now try editing a file (try the README) and then do:
$ git add -A $ git commit -m "memo"
$ git push Enumerating objects: 3, done. Counting objects: 100% (3/3), done. Delta compression using up to 8 threads Compressing objects: 100% (3/3), done.

How to commit/upload to git
Note: For Ardika, follow the How to add SSH key and push using SSH steps above to commit and push via your mac/pc.
To commit:
git add [new file] git commit -m "memo" git push
If you get: git@github.com: Permission denied (publickey), follow the steps below...
Workaround (need to find permanent fix):
- I put this as a script:
eval "$(ssh-agent -s)" ssh-add ~/.ssh/<githubkey> ssh -T git@github.com
- Then run:
git remote set-url origin git@github.com:ardikas/terraform git add * || git add [file] git commit -m "memo" git push
$ git config --list user.email=<my email> user.name=ardikas core.repositoryformatversion=0 core.filemode=true core.bare=false core.logallrefupdates=true remote.origin.url=https://github.com/ardikas/shell-scripts remote.origin.fetch=+refs/heads/*:refs/remotes/origin/* branch.master.remote=origin branch.master.merge=refs/heads/master
