Git Reference
I’ve been using git
for years now but there are commands I use every day while others, not so much.
New Repository
Create a new repository on GitHub at https://repo.new/. Then locally, run:
echo "# anything" >> README.md
git init
git add README.md
git commit -m "first commit"
git branch -M main
git remote add origin https://github.com/<your-gh-username>/<repository-name>
git push -u origin main
Removing something from git
Because I forgot my .gitignore
and the node_modules directory got committed again. Create the .gitignore
file this time and run:
git rm -r --cached node_modules
git commit -am "Removed node_modules directory"
Committing a modified file in a submodule
cd
inside the submodule directory then add and commit to git from there. You can then go to your project directory and add and commit to git as normal.
Pushing a repo to a different GitHub account
Configure the name and email for the particular repository:
git config user.name "<github username>"
git config user.email "<github email>"
Modify your ssh config at ~/.ssh/config
:
Host github.com-acct1
User git
HostName github.com
IdentityFile ~/.ssh/github_private_key1
IdentitiesOnly yes
Host github.com-acct2
User git
HostName github.com
IdentityFile ~/.ssh/github_private_key2
IdentitiesOnly yes
git push
should now be authenticated for the new account.
