Dear DevOps Engineer!! this post is full of experimenting with git commands running most of them on the 'Git Bash' window in my laptop. I've collected three things about each git command.
- git command syntax
- What this git command will do - short descriptions
- An example command that I've executed
- Screenshot of that command execution
How do I Start a Fresh repository in Git CLI(local repo)?
You need to create a folder where you would like to start your coding project. The code can be web-site related where you can have multiple directories involved such as HTML files into a folder, all images to be used in the website in a folder, CSS files into a folder, etc. First, make the folder structure for you project then at the root of the project need to initialize the project. To create empty repo or re-initializing a repo
Syntax :
git init
Note: It is always better to have a fresh directory created and then run the above command to initialize a local Git repository.

Getting a remote repository to your git client - Local system/Laptop
You can have the remote repository either public or private teams on the following SCM clouds:
- GitHub
- GitLab
- BitBucket
git clone Syntax:
git clone ssh://git@github.com/[username]/[repository-name].git
Create a local copy of a remote repository of GitHub or Gitlab. Make sure that you're doing first time in that folder, it should not have the same repo that means if your re-run the same command it cannot work.
Please make sure you have the correct access rights and the remote repository exists
Example of using gitlab URL:
git clone https://github.com/BhavaniShekhar/vtdevops2021feb.git
 |
| Vybhava : git clone |
Syntax:
git commit -m "[commit message]"commit changes
Example:
git commit -m "some message"
 |
| git commit command |
Syntax:
git checkout -b [branch name origin/[branch name]
Clone a remote branch and switch to it

| Differences between git checkout & switch command |
Syntax:
git checkout [branch name]
Switch to a branch
