The 'commit' command is used to save your changes to the local repository.
The risk posed by this is minimal, since even though an observer may be able to tie the MAC addresses 00:00:00:01 and 00:00:00:02 together using the common RPI, the duration of both MAC addresses is no longer than a single RPI period (10 minutes). When the RPI rotates, the MAC address rotates again, making it difficult to track the association of either the MAC address or RPI to a common device. I do not know what github for Mac rollback does, but it seems that you would be better off using command line to resolve the issue at hand: git cherry-pick -abort - to stop any cherry-picking in progress. Git branch -va - will show you where are your pointers right now. Make sure your working directory is clean: git status - should not show any modified or staged files. Git commit on Mac. I'm following the Git basics tutorial in the Terminal on my Mac and when I get to the part where you type 'git commit' in the command line and then add the comment 'Added a README file.' , I can't seem to save and close to complete the commit. In the tutorial and if you use Treehouse's Console, you can hit ^X to exit and save.

Note that you have to explicitly tell Git which changes you want to include in a commit before running the 'git commit' command. This means that a file won't be automatically included in the next commit just because it was changed. Instead, you need to use the 'git add' command to mark the desired changes for inclusion.
Also note that in Git (not like in Subversion), a commit is not automatically transferred to the remote server. Using the 'git commit' command only saves a new commit object in the local Git repository. Exchanging commits has to be performed manually and explicitly (with the 'git fetch', 'git pull', and 'git push' commands).

Important Options
-m <message>
Sets the commit's message. Make sure to provide a concise description that helps your teammates (and yourself) understand what happened.
-a
Includes all currently changed files in this commit. Keep in mind, however, that untracked (new) files are not included.
--amend
Rewrites the very last commit with any currently staged changes and/or a new commit message. Git will rewrite the last commit and effectively replace it with the amended one. Note that such a rewriting of commits should only be performed on commits that have not been pushed to a remote repository, yet.
Tip
Easy Committing in Tower
In case you are using the Tower Git client, committing is very easy: just check the changed files you want to include and enter your commit message. You can even add individual chunks and lines from a file (instead of the whole file)!

Usage Examples
For a basic workflow, you can use the 'git add' command to stage changes for the next commit. The actual commit command will then wrap up the mentioned changes in a new commit object:
If you have lots of changed files in your working copy - and want all of them included in the next commit - you can make use of the '-a' parameter and thereby omit the 'git add' step:
The '--amend' option comes in handy, for example, when you mistyped the last commit's message or forgot to add a change. The following example will correct the very last commit by overwriting its message and adding another change:

The
git commit
command captures a snapshot of the project's currently staged changes. Committed snapshots can be thought of as “safe” versions of a project—Git will never change them unless you explicitly ask it to. Prior to the execution of git commit
, The git add
command is used to promote or 'stage' changes to the project that will be stored in a commit. These two commands git commit
and git add
are two of the most frequently used.Git commit vs SVN commit
While they share the same name,
git commit
is nothing like svn commit
. This shared term can be a point of confusion for Git newcomers who have a svn background, and it is important to emphasize the difference. To compare git commit
vs svn commit
is to compare a centralized application model (svn) vs a distributed application model (Git). In SVN, a commit pushes changes from the local SVN client, to a remote centralized shared SVN repository. In Git, repositories are distributed, Snapshots are committed to the local repository, and this requires absolutely no interaction with other Git repositories. Git commits can later be pushed to arbitrary remote repositories.How it works
At a high-level, Git can be thought of as a timeline management utility. Commits are the core building block units of a Git project timeline. Commits can be thought of as snapshots or milestones along the timeline of a Git project. Commits are created with the
git commit
command to capture the state of a project at that point in time. Git Snapshots are always committed to the local repository. This is fundamentally different from SVN, wherein the working copy is committed to the central repository. In contrast, Git doesn’t force you to interact with the central repository until you’re ready. Just as the staging area is a buffer between the working directory and the project history, each developer’s local repository is a buffer between their contributions and the central repository.This changes the basic development model for Git users. Instead of making a change and committing it directly to the central repo, Git developers have the opportunity to accumulate commits in their local repo. This has many advantages over SVN-style collaboration: it makes it easier to split up a feature into atomic commits, keep related commits grouped together, and clean up local history before publishing it to the central repository. It also lets developers work in an isolated environment, deferring integration until they’re at a convenient point to merge with other users. While isolation and deferred integration are individually beneficial, it is in a team's best interest to integrate frequently and in small units. For more information regarding best practices for Git team collaboration read how teams structure their Git workflow.
Snapshots, not differences
Aside from the practical distinctions between SVN and Git, their underlying implementation also follows entirely divergent design philosophies. Whereas SVN tracks differences of a file, Git’s version control model is based on snapshots. For example, a SVN commit consists of a diff compared to the original file added to the repository. Git, on the other hand, records the entire contents of each file in every commit.
This makes many Git operations much faster than SVN, since a particular version of a file doesn’t have to be “assembled” from its diffs—the complete revision of each file is immediately available from Git's internal database.
Git's snapshot model has a far-reaching impact on virtually every aspect of its version control model, affecting everything from its branching and merging tools to its collaboration work-flows.
Common options
Github Commit All
Commit the staged snapshot. This will launch a text editor prompting you for a commit message. After you’ve entered a message, save the file and close the editor to create the actual commit.
Commit a snapshot of all changes in the working directory. This only includes modifications to tracked files (those that have been added with
git add
at some point in their history).A shortcut command that immediately creates a commit with a passed commit message. By default,
git commit
will open up the locally configured text editor, and prompt for a commit message to be entered. Passing the -m
option will forgo the text editor prompt in-favor of an inline message.A power user shortcut command that combines the
-a
and -m
options. This combination immediately creates a commit of all the staged changes and takes an inline commit message.This option adds another level of functionality to the commit command. Passing this option will modify the last commit. Instead of creating a new commit, staged changes will be added to the previous commit. This command will open up the system's configured text editor and prompt to change the previously specified commit message.
Examples

Github Commit Message
The following example assumes you’ve edited some content in a file called
hello.py
on the current branch, and are ready to commit it to the project history. First, you need to stage the file with git add
, then you can commit the staged snapshot.This command will add
hello.py
to the Git staging area. We can examine the result of this action by using the git status
command.The green output new file:
hello.py
indicates that hello.py
will be saved with the next commit. From the commit is created by executing:This will open a text editor (customizable via
git config
) asking for a commit log message, along with a list of what’s being committed:Github Commit Keywords
Git doesn't require commit messages to follow any specific formatting constraints, but the canonical format is to summarize the entire commit on the first line in less than 50 characters, leave a blank line, then a detailed explanation of what’s been changed. For example:
It is a common practice to use the first line of the commit message as a subject line, similar to an email. The rest of the log message is considered the body and used to communicate details of the commit change set. Note that many developers also like to use the present tense in their commit messages. This makes them read more like actions on the repository, which makes many of the history-rewriting operations more intuitive.

To continue with the
hello.py
example above. Let's make further updates to hello.py
and execute the following:This will once again, open up the configured text editor. This time, however, it will be pre-filled with the commit message we previously entered. This indicates that we are not creating a new commit, but editing the last.
Summary
The
git commit
command is one of the core primary functions of Git. Prior use of the git add
command is required to select the changes that will be staged for the next commit. Then git commit
is used to create a snapshot of the staged changes along a timeline of a Git projects history. Learn more about git add
usage on the accompanying page. The git status
command can be used to explore the state of the staging area and pending commit.The commit model of SVN and Git are significantly different but often confused, because of the shared terminology. If you are coming to Git from a personal history of SVN usage, it is good to learn that in Git, commits are cheap and should be used frequently. Whereas SVN commits are an expensive operation that makes a remote request, Git commits are done locally and with a more efficient algorithm.
