How to do things with Git

Remote management

View current remote url

git remote -v

Disassociate an existing remote

git remote rm {{name-of-remote-i.e.-origin}}

Associate a new remote

git remote add origin git@github.com:username/name-of-repo.git
git branch -M main
git push -u origin main
# or checkout existing branch
git checkout master

Account management

Change username for repo

git config user.email "your_email@abc.com"

Set user for repository

git config user.name "Mona Lisa"
git config user.email "mona.lisa@example.com"
# Verify config
cat .git/config

Branch management

Push all branches to origin

git push --all origin

Rename branch

git branch -m old-branch new-branch-name

History management

Delete all commit history

Deleting the .git folder may cause problems in your git repository. If you want to delete all your commit history but keep the code in its current state, it is very safe to do it as in the following:

Checkout: git checkout --orphan latest_branch

Add all the files: git add -A

Commit the changes: git commit -am "commit message"

Delete the branch: git branch -D main

Rename the current branch to main: git branch -m main

Finally, force update your repository: git push -f origin main

PS: this will not keep your old commit history around
