There is no way to create a file without opening it There is os.mknod("newfile.txt") (but it requires root privileges on OSX). The system call to create a file is actually open() with the O_CREAT flag. So no matter how, you'll always open the file.

So the easiest way to simply create a file without truncating it in case it exists is this:

open(x, 'a').close() 

Actually you could omit the .close() since the refcounting GC of CPython will close it immediately after the open() statement finished - but it's cleaner to do it explicitely and relying on CPython-specific behaviour is not good either.

In case you want touch's behaviour (i.e. update the mtime in case the file exists):

import os def touch(path):     with open(path, 'a'):         os.utime(path, None) 

You could extend this to also create any directories in the path that do not exist:

basedir = os.path.dirname(path) if not os.path.exists(basedir):     os.makedirs(basedir)

Of course there IS a way to create files without opening. It's as easy as calling os.mknod("newfile.txt"). The only drawback is that this call requires root privileges on OSX.

What is Git:

"Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency"

Git is a distributed peer-peer version control system. Each node in the network is a peer, storing entire repositories which can also act as a multi-node distributed back-ups. There is no specific concept of a central server although nodes can be head-less or 'bare', taking on a role similar to the central server in centralised version control systems.

What is GitHub:

"GitHub is a web-based Git repository hosting service, which offers all of the distributed revision control and source code management (SCM) functionality of Git as well as adding its own features."

Github provides access control and several collaboration features such as wikis, task management, and bug tracking and feature requests for every project.

You do not need GitHub to use Git.

GitHub (and any other local, remote or hosted system) can all be peers in the same distributed versioned repositories within a single project.

Github allows you to:

  • Share your repositories with others.
  • Access other user's repositories.
  • Store remote copies of your repositories (github servers) as backup of your local copies.

Git — The version control tool that GitHub is built on top of.

GitHub — Our company and the name of our software. We build software and websites to help you interact with Git repositories in a nice way.

GitHub.com — The website you log into to view repositories online.

GitHub Desktop — An application that you can install on your computer to help you synchronize local code with GitHub.com.

There are a number of obvious differences between Git and GitHub.

Git itself is really focused on the essential tasks of version control. It maintains a commit history, it allows you to reverse changes through reset and revert commands, and it allows you to share code with other developers through push and pull commands. I think those are the essential features every developer wants from a DVCS tool.

Git versus GitHub Comparison Chart

No Scope Creep with Git

But one thing about Git is that it is really just laser focused on source code control and nothing else. That's awesome, but it also means the tool lacks many features organizations want. For example, there is no built-in user management facilities to authenticate who is connecting and committing code. Integration with things like Jira or Jenkins are left up to developers to figure out through things like hooks. Basically, there are a load of places where features could be integrated. That's where organizations like GitHub and GitLab come in.

Additional GitHub Features

GitHub's primary 'value-add' is that it provides a cloud based platform for Git. That in itself is awesome. On top of that, GitHub also offers:

  • simple task tracking
  • a GitHub desktop app
  • online file editing
  • branch protection rules
  • pull request features
  • organizational tools
  • interaction limits for hotheads
  • emoji support!!! :octocat: :+1:

So GitHub really adds polish and refinement to an already popular DVCS tool.

Git and GitHub competitors

Sometimes when it comes to differentiating between Git and GitHub, I think it's good to look at who they compete against. Git competes on a plane with tools like Mercurial, Subversion and RTC, whereas GitHub is more in the SaaS space competing against cloud vendors such as GitLab and Atlassian's BitBucket.

No GitHub Required

One thing I always like to remind people of is that you don't need GitHub or GitLab or BitBucket to use Git. Git was released in what, 2005? GitHub didn't come on the scene until 2007 or 2008, so big organizations were doing distributed version control with Git long before the cloud hosting vendors came along. So Git is just fine on its own. It doesn't need a cloud hosting service to be effective. But at the same time, having a PaaS provider certainly doesn't hurt.

Working with GitHub Desktop

By the way, you mentioned the mismatch between the repositories in your GitHub account and the repos you have locally? That's understandable. Until you've connected and done a pull or a fetch, the local Git repo doesn't know about the remote GitHub repo. Having said that, GitHub provides a tool known as the GitHub desktop that allows you to connect to GitHub from a desktop client and easily load local Git repos to GitHub, or bring GitHub repos onto your local machine.

GitHub Desktop

I'm not overly impressed by the tool, as once you know Git, these things aren't that hard to do in the Bash shell, but it's an option.
