No. This is not a tutorial about git. I doubt you can go from zero to anything using this. This is a collection of notes about git that I made for myself. You are free to read them and benefit from them if they help you at all, though.
In git, a snapshot is the state of a repository in a point in time.
In git, cherry-pick is used to apply the changes introduced by some existing commits into the current working tree. The description of the command:
Given one or more existing commits, apply the change each one introduces, recording a new commit for each. This requires your working tree to be clean (no modifications from the
If the exclusion pattern is somehow specific to your repository, then it
should go into the
.git/info/exclude file, because it is not
propagated during clone operations. Its pattern format and treatment
is the same as .gitignore files.
Ranges of commits
(a..b) may be passed to
git log. This takes all
commits reachable from
b but not from
a. For instance, git log
master~10. One can also
pass the symmetric difference between two references
the third dot.) With
git log this takes the set of commits that are
b, but not from both.
Like in Subversion, the Centralized Workflow uses a central repository
to serve as the single point-of-entry for all changes to the project.
Instead of trunk, the default development branch is called
all changes are committed into this branch. This workflow doesn’t
require any other branches besides
The Feature Branch Workflow still uses a central repository, and
master still represents the official project history. But, instead of
committing directly on their local master branch, developers create a
new branch every time they start work on a new feature. Feature branches
should have descriptive names, like
issue-1061. The idea is to give a clear, highly-focused purpose to
each branch. Remember to do a
git rebase upstream before pushing your
changes to the remote.
The Gitflow Workflow is the ideal workflow for large teams or multi-team
master branch on this workflow serves only as an
abridged version of the story of the project. Actual development happens
development branch and feature branches interact with it only.
When a release is needed, a
release branch is derived from the
development branch and polished until it can be squashed and merged
The Forking Workflow is the last and most modern Git Workflow. It gives each and every developer their own fork of the repository. The result is a distributed workflow that provides a flexible way for large, organic teams (including untrusted third-parties) to collaborate securely. This also makes it an ideal workflow for open source projects. It’s important to understand that the notion of an “official” repository in the Forking Workflow is merely a convention. From a technical standpoint, Git doesn’t see any difference between each developer’s public repository and the official one. In fact, the only thing that makes the official repository official is that it’s the public repository of the project maintainer or of the project’s organization. All of these personal public repositories are really just a convenient way to share branches with other developers. Everybody should still be using branches to isolate individual features, just like in the Feature Branch Workflow and the Gitflow Workflow. The only difference is how those branches get shared. In the Forking Workflow, they are pulled into another developer’s local repository, while in the Feature Branch and Gitflow Workflows they are pushed to the official repository.
Note that it is possible to fork by SSH’ing into the server and running
git clone to copy it to another location on the server. Forking is
basically just a server-side clone.
This subsection is largely based on the amazing Comparing Workflows by the guys at Atlassian.
