Git

Git is a way to upload your packages onto a version control system of your choice (as in either Gitlab, Github, or other version control site of your choice)

Here are some key commands to know:

CLI instructions:

Git global setup:

git config --global user.name "Shwetha Jayaraj"
git config --global user.email "shwetha.jayaraj@uconn.edu"

Create a new repository:

git clone git@gitlab.com:shwetha729/coding-tips.git
cd coding-tips
git switch -c main
touch README.md
git add README.md
git commit -m "add README"
git push -u origin main

When you have an empty folder to add to git repo

Git init 
Git add . 
Git status 
Git commit -m ‘your message’ # commit to local repo
Git remote add origin ‘urlname’ # add url from repo 
Git push -u origin master # push local content to github

Push an existing folder:

cd existing_folder
git init --initial-branch=main
git remote add origin git@gitlab.com:shwetha729/coding-tips.git
git add .
git commit -m "Initial commit"
git push -u origin main

Example 2: pushing changes from commit into your branch

git push [nameofyournewremote] [url]

Example 3:

Push an existing Git repository:

Example 1:

cd existing_repo
git remote rename origin old-origin
git remote add origin git@gitlab.com:shwetha729/coding-tips.git
git push -u origin --all
git push -u origin --tags

Example 2:

Git remote add origin https://github.com/username/repo.git
Git push -u origin master

Example 3: Forking an existing repo

#  fork the original repo  on top  right corners
git clone  [git url]
git remote -v # syncs forked repo 
git remote add upstream [git clone url]

Example 4: Push changes from your commit into your branch

git push [nameofyournewremote]  [url]

Branch controls

Create a new branch on git:

$ git branch <name_of_your_new_branch>

View all branches:

git branch -a

Add a new remote for your branch:

git remote add [name_of_your_remote] [name_of_your_new_branch]

Delete a branch on your local filesystem:

$ git branch -d [name_of_your_new_branch]

# or to force deletion 

$ git branch -D [name_of_your_new_branch]

Delete a branch on github:

$ git push origin :[name_of_your_new_branch]

Go to desired branch

git checkout [branchname]
# OR 
#git checkout --

SSH things:

CREATE new ssh key:

For example, for ED25519:

ssh-keygen -t ed25519 -C "<comment>"

For 2048-bit RSA:

ssh-keygen -t rsa -b 2048 -C "<comment>"

and then

Generating public/private ed25519 key pair. Enter file in which to save the key (/home/user/.ssh/id_ed25519):

press enter twice.

Enter passphrase (empty for no passphrase): Enter same passphrase again:

then enter passphrase.

COPY public key to Gitlab account for example (MacOS):

tr -d '\n' < ~/.ssh/id_ed25519.pub | pbcopy

Replace id_ed25519.pub with your filename. For example, use id_rsa.pub for RSA.

Then sign in > top right > Preferences > SSH Keys > paste contents into Key box > type description into Title box > Add Key .

VERIFY that you can connect :

ssh -T git@gitlab.com
