Working with Git on the command line (Linux)
Git basics
Simple instruction how to handle git on the command line
Check if Git is installed and ready
|
1 |
git --version |
If not, you can install git using (on Ubuntu)
|
1 |
sudo apt install git |
Set username and email
Every commit is marked with username and email to identify the autor
|
1 2 |
git config --global user.name "YOUR_USERNAME" |
You can check the informations using
|
1 |
git config --global --list |
(1) Initialize a local directory for Git
If you want to include your local directory to version control, use init to tell Git what to track
|
1 |
git init |
.git directory is created including configuration files
(2) Clone a repo
If you want to start working on some existing project, you can clone it (copy) to your local machine. You can use HTTPS or SSH. Using HTTPS you have to put credentials every time, using SSH only first time.
HTTPS:
|
1 |
git clone https://gitlab.com/some-repo/ |
SSH:
|
1 |
git clone git@gitlab.com:some-repo |
