           [--super-prefix=<path>] [--config-env=<name>=<envvar>]
           <command> [<args>]

These are common Git commands used in various situations:

  • Configure Git

    1. Open Terminal

      git config --global user.name "<your name>"
git config --global user.email <your email>
git config --global init.defaultBranch main
git config --global pull.rebase false

    3. Type git config --list to verify. Checkout for this output :-

      $ git config --list
core.repositoryformatversion=0
core.filemode=true
core.bare=false

user.email=<your email>
init.defaultbranch=main
pull.rebase=false

  • Add Github SSH

    We are assuming that you already have a github account.

    1. Generate a New Key

      Open termianak and enter the following command :-

      $ ssh-keygen -t rsa -C "<your email"

      • Press Enter when prompted to enter a file, this will save the keys to the default location i.e. ~/ssh/id_rsa

      • When prompted to enter a password, when you hit enter without typing anything that means no password. Which is okay.

      • The output in the Terminal should look like this :-

        Your identification has been saved in id_rsa.
Your public key has been saved in id_rsa.pub.
The key fingerprint is:
SHA256:C3AB8FF13720E8AD9047DD39466B3C8974E592C your@email_address.com
The key's randomart image is:
+---[RSA 2048]----+
| .       =   ..  |
|o . . o + = ..   |
| =.o o o o o  .  |
|+ +o. .  ..  . . |
|.+E  .  S   o o..|
|..     .  .o . .+|
|        o  oo .o+|
|       . o  ==o.=|
|        . .+=B=o |
+----[SHA256]-----+

        Awesome! You have your private and public keys saved 🎉

    2. Add the new key to your system

      In your Terminal, run :-

      $ ssh-add ~/.ssh/id_rsa
