Git - Basic

Git daily use manual

Default editor​

git config --global core.editor vim

Encoding​

Please, if your team has Windows developers AND/OR you want to avoid LF / CRLF problems (more info)...

git config --global core.autocrlf false

Modes​

If you enconter several files changed with:

old mode 100644
new mode 100755

Run the following git config to set it GLOBALLY.

git config --global core.filemode false

Authentication​

First you'll need to authenticate yourself, as most of the "corporative repositories" are private.

A nice approach to do so is to use SSH Keys.

Config your git to identify yourself:

git config --global user.email "<your git email>"
git config --global user.name "<your name>"

SSHKey​

  1. Follow the instructions here to get your SSHKey.

  2. Add your pubkey to your git provider account

GPGKey​

  1. Follow the instructions here to get your GPGKey.

  2. Add your public GPGKey (result from $GPGKEY_PB) to your git provider

  3. Set your environment to use your GPG Key

git config --global user.signingkey $GPGKEY_FP
git config --global commit.gpgsign true
git config --global tag.gpgsign true
git config --global gpg.program "gpg"

Initializing a empty repo​

  1. Create a directory 
mkdir <repository_name>
  1. Enter on it, initialize a git repository and set the remote url
cd <repository_name>
git init
git remote add origin git@gitlab.com:example/example-project.git

  1. Create a file or start doing your code.

  2. Add the modifications, you can check those by running git status

git add <file(s)/dir(s)>
  1. Finally, commit the changes with a message explaining the changes.
git commit
  1. Push the commit to the git remote repository
git push origin <branch_name>

Getting a remote branch​

If you do need to get a remote branch:

git fetch
git pull origin branch-name:branch-name

The remote branch will be available in your local machine.

Comparing branches​

For instance, you need to see what does the branch dev has that master doesn't:

git diff master...dev

;)

Releases and Tags​

When you need to deliver the code, you need to create a Tag and then Release it so the source-code will be provided as a zip or tar.gz file.

In the example, we'll release the version 1:

git tag v1.0.0
git push origin v1.0.0

Then, you need to go the the git provider web interface and create a Release:

  • Go to the repository URL, Tag section
  • Create release

// TODO improve

Now you'll have a zip file containing the repository source-code.
