01219245/git

This is part of 01219245.

In this course, we will use Git as our software version control tool. There are various UI clients for Git, but we will use the command-line version.

Preparations

Install Git: go to download page, download and install the command-line version.

• Additional info for Windows users:
  • When the installer ask you to select components, you can tick off the "Windows Explorer integration".
  • When the installer ask you the option to "Adjusting your PATH environment", choose "Run Git from Windows Command Prompt".

In-class practice

1. Basic git with HTML

You should watch the first part of the clip, Git (Part 1), to get some idea of the exercise.

1.1 Creating a new repository

1. We will work with command line. For Windows user, use cmd.exe. For Mac/Linux, open a terminal program.

2. Find a location in your file system, and create a new directory/folder for the practice. Let's call the directory homepage. The command for that is mkdir.

mkdir homepage

Then change the current directory to homepage:

cd homepage

3. We will create a repository in that directory. To create a new Git repository, simple call

git init

If the command runs successfully, git would say something like this:

Initialized empty Git repository in /xxx/xxxx/homepage/.git/

4. If you call,

git status

to see the status of the repository, Git would reply that there's nothing to commit

# On branch master
#
# Initial commit
#
nothing to commit (create/copy files and use "git add" to track)

1.2 Your (first) HTML page

Hyper-Text Markup Language (HTML) is the language that describes the web. Almost everything we see on the web is written in HTML, including the current page you are viewing.
