It's often confusing the different commands needed to interact and efficiently work with GIT. We need a handleful of the useful ones. In this short article, I am going to show you the regular unavoidable task performed by modern developers.
BASIC COMMANDS
- Create a repository on github (Web)
- Delete a mistaken .env from remote:
git rm --cached .env - Set up global username
git config --global user.name <"ur username"> - Set up global email
git config --global user.email <"ur password"> - Add remote url to local
git remote add origin <url> - Innitialise a git repository locally
git init - Git clone
git clone -b <branch> <remote_repo> - Push code to remote
git push origin <branch name> - Check remote connection
- Make or create a new branch
git checkout -b "master" - Updated local branch with remote changes
git pull - Create a branch
git checkout -b myNewBranch - Pull request
git pull <remote> <branch> - Merge between branches
- Check for changes in the tree state
git status - Check the repo remote URL
git remote -v - Check remote url
git config --get remote.origin.url - Undo a merge action to its last commit
git reset --hard - Undo git init
rm -rf .git - Change git remote origin
git remote set-url origin your-git-origin-url-path - Undo git add .
git reset - check for latest commit hash:
git log --oneline - Undo latest push:
git reverse hash-value - Delete branch from local
git branch -D my-local-branch - Delete branch from remote
git push -d origin <branch-name> - Rename local branch
git branch -m <old-branch> <new-branch>
Create a repository on github
There are two methods to this;
- Create a repo on GitHub website and
- Create a repo locally
How to create a git repository on GitHub website; To do this, navigate to your newly created GitHub account, follow the prompts, make sure you have confirmed your email address. I created a new account for this demo. The image below is only for new sign-ups with fresh GitHub account.
If you have an already existing account, your screen will look like the image below:
After clicking the repo button, you will be prompted to give a name to the repo and optionally add a readme to the new repo folder, ones this done, go ahead and click the create repo green button as the final step.
Innitialize a git repo locally
Fire up your vsCode, navigate to the command line and type this on the command line git init. This command innitialises a git repo locally on your pc.
Save your code
Write code on your vsCode, Before saving your code, be sure your remote repo(online) is connected with your local repo. Let us assume we have typed a line of code for the first time and we want to check connection with the remote, type: git remote if you get a response like fatal: not a git repository (or any of the parent directories): .git, then it means you are not connected to remote. *connect with the remote: * git remote add origin url.
Git clone git clone url
Push code to github from local
You can only push code to GitHub from local when you are rightly connected to the remote as illustrated. Follow the steps to push your first code to remote.
git add .: This command saves your work in the staging area
git commit -m "commit message" This command saves your code to GitHub.git push origin master`: the origin refers to the remote repo while "master" is the branch we are committing code to.
**push code to remote:**
*issues from pushing to remote can be solved with this 2 steps
git clone urlgit push
Check remote connection: git status
Create a branch git branch branch-name
Check tree/branch status
If you recall that GitHub repository chain is like a tree with branches, you may want to track which brach you are currently working on with this command: git branch, it shows you your current working branch.
Pull request(PR): git pull
If you recall, GitHub is a great place for coding teams to collaborate easily. You may have had code commits from other team members on the GitHub repo that has not reflected on your local machine, to check this, you need to type git status, this will let you know of any changes to the current file, to enable a git pull.
Merge between branches
To merge a branch with another, you need to be sure which branch you are currently on. You can use git merge branch or git rebase branch
