Let’s Git Started: local operations
In this mini tutorial you will receive the basic knowledge to work with GIT in your local machine
GIT is a great tool when combined with an online repository, but this is the topic of next week.

3. Let’s Git Started: local operations
Let’s Git Started: local operations
GIT is free, open source software.
Works from GUI and from terminal (command-line)
On the Lab machines you can launch it with:
GIT Bash (Windows)
git (Linux – command line only)

4. Let’s Git Started: command line ?!??
Let’s Git Started: command line ?!??
Don‘t panic!
You need just three commands: (but you can learn more...)
Change directory: cd
List files in a directory: ls
Create a new directory: mkdir <name_of_dir>

5. Let’s Git Started: initialization
Let’s Git Started: initialization
Open a terminal or GIT Bash.
Set the language to English (if you like)
Browse to the directory with the project template files.
Initialize your first GIT repository
$ export LANG=en_us
$ cd /path/to/your/files/
$ git init

Let’s Git Started: introduction
Introduce yourself to GIT.

7. Let’s Git Started: introduction
Let’s Git Started: introduction
Introduce yourself to GIT.
$ git config --global user.name "Your Name"
$ git config --global user.

8. Let’s Git Started: give GIT tasks
Let’s Git Started: give GIT tasks
Tell GIT which files you would like to track for changes.
Take a snapshot (commit) of all tracked files
$ git add file1 file2
$ git add .
$ git commit –m “This is my first commit”

9. Let’s Git Started: do your job…
Let’s Git Started: do your job…
Do any modification to the content of the files.
Get the update of the status of the repository
$ git status
Visualize the differences in the terminal.
Visualize the differences in a GUI client
$ git diff
$ gitk ; git gui ; gitx (for MAC)

10. Some hints how to use GIT for your code
Some hints how to use GIT for your code
Commit often.
Use appropriate commit messages.
Do not rename the file names manually (use git mv)
New files are not automatically indexed, must be added.
Careful with git add .
Rather choose the files: git add file1
Write a .gitignore file or use git ignore for files that you never want to commit (e.g. big datasets)
