GIT VERSION CONTROL

Once Git is installed you can initialise a name and an email address to 'sign' the commits.

git config --global user.name "your-name" git config --global user.email [email protected]

Basic Commands

Setup a directory

mkdir news cd news

To initialise a git repository

git init

To check if it worked find a .git directory

ls -a

Use an editor to add some text to a file.

If you are unsure of a text editor try nano.

nano fake-news.txt

'''

Lochness Monster was sighted in China.

'''

We have now created a text file in out git repository but we haven't told git to record the changes.

git status

If we want to commit this file we first have to add it to the commit

git add fake-news.txt

Now to commit the changes.

git commit

Deleting and moving files

git rm

git mv

Comparing to previous versions

To see the commit log

git log

To compare differences you need to specify the reference number from the git log

git diff 9ac1f1648573bf25b521622304a8bc0b0c3be902

You can also have a GUI to look at your commit history.

gitk

You can use blame to see the date, time, user and which commit each line was modified.

git blame fake-news.txt

Breaching & Merging

To make a new branch

git branch executive-order

By default we start out on master. Now we need to change to the new branch

git checkout executive-order

Now we can add some more text

'''

Bunyip tracks found on Hawaiian beach

'''

Now compare to the master

git diff master

To merge our branch with master we need to checkout the master branch

git checkout master

git merge executive-order

To delete a branch

git merge -d executive-order

Dealing with Conflicts

If you have a conflict a message will show:

""" Auto-merging fake-news.txt CONFLICT (content): Merge conflict in fake-news.txt Automatic merge failed; fix conflicts and then commit the result. """

In the files you will see arrows like these.

`"""

<<<<<<< HEAD Yeti tracks found on Hawaiian beach. Shocking!!!

Yeti tracks found on Hawaiian beach. Smashing!!!

executive-order

"""`

Everything between <<<< and ==== is in your HEAD repository and everything between ==== and >>>> is in the repository you are merging from.
