Configure Tooling:

GIT comes with a tool called git config that lets you get and set configuration variables that control all aspects of how Git looks and operates.

1.To View all of account settings:

$ git config --list --show-origin

-Git is to set your user name and email address. This is important because every Git commit uses this information, and it’s immutably baked into the commits you start creating.

-To use Git we need to attach username and email to commit any transactions

2.To set Username:

$ git config --global user.name "abc"

3.To set Email:

$ git config --global user.email abc@xyz.com

4.To set main as the default branch:

$ git config --global init.defaultBranch main

5.To check the configuration settings use:

$ git config --list

6.To get help for Config:

$ git help config

Create Repositories:

There are two methods to obtain a Git repository:

1.You can take a local directory that is currently not under version control, and turn it into a Git repository.

2.You can clone an existing Git repository from elsewhere.

●To turn a directory into a Git repository:

$ git init

●To clone a existing repository located at [url]:

$ git clone [url]

GIT Branching:

Branch operation allows creating another line of development

●To Create a new branch:

$ git branch [branch_name]

●To checkout a new branch named [branch_name]:

$ git checkout [branch_name]

●To delete an existing branch:

$ git branch -d [branch_name]

●To merge specific branch to current branch:

$ git merge [branch]
