GitHub - 2 Developers working at the same time - github

Some friends of mine and me are trying to code an application. We are probably going to using the Eclipse IDE and also want to use GitHub (because we heard, it is the leading platform for team-developments).
I think, I understood this whole Push, Pull and Commit thing.
Let's say my friend is pushing a new update for our project; but in the meantime I'm working on something else in the same project. What happens if I pull the updated version? Will the code, which just i wrote, be overwritten by the GitHub-project?
If yes, is there any way to prevent this in a simple way?

No , when someone pushes at a remote server in your case GitHub , only the remote branches gets updated . When you pull from the remote server the remote branches in your local computer gets updated to their new position , however you local master branch remains the same , you can merge your master branch with that of the remote master branch in order to combine your works . If same file has been edited , then there will be conflicts and you have to resolve them using some merge tool . However if no same files are edited then merging will be smooth. If you want to ignore your friend's work just rebase your commit over his

How do I get my Git commits to show on github?

I am new to this world and enrolled in a bootcamp. We created a GitHub account a few months ago. At the time everything worked fine. I was able to make changes locally and commit them via the command line, fork repos, clone them, make changes, and commit. All the good stuff.
Now after not using GitHub for much recently we are back working on a project there. However, now whenever I make a commmit it is not tracking on GitHub. When I make the change, add it and commit it I receive the below message and no changes show on GitHub.
1 file changed, 1 insertion(+), 1 deletion(-)
I am not sure what has happened. Is it possible I have moved the files to the wrong directory? At this point I am not sure how to tell what directory I need to have the files in. Any insights would be much appreciated.
You need to git push to send your local changes to GitHub.

GitHub Desktop doesnt pick and push the entire repository

I am using GitHub desktop application on my local machine and when I create and complete my repository(web directory)on my local machine, then I push it GitHub online through desktop application. But here is my problem:
Sometimes it doesn't pick and push all of the files/folders from my local repository, it only pick 3 files, while my repository has 5 folders and one inex.html file.
And sometimes it works perfectly fine. I never understand where is my problem. Any thoughts on this?
Do a git status before your push, as well as a git show HEAD to check the content of your last commit.
That way, you will see if there remain some files not added to the index or not committed.
And you will see if every files you wanted is in a commit.
If one file is consistently ignored, see if it is actually ignored by Git with:
git check-ignored -v -- a/file

GitHub client cannot sync after changes made to some files

I have a git repository in which I work in collaboration with some people but I cannot sync anymore. I am using the GitHub Windows client application on Windows 7:
Last time I synced, the operation succeeded and I ended up with a perfect copy of the latest code.
Next, I made some simple changes to a few files, but did not commit anything yet.
In the meantime, someone else made changes to some other files.
In order to see the changes of the repository, I'm trying to sync again.
GitHub client reports "Sync failed".
Now I am wondering if this is normal behavior or if there is something wrong with my repository ? Shouldn't I be able to sync the repository and get latest files even though I am making some changes that are still not committed ?
Thanks.
When you got this kind of error just try to open a git shell and type git status into your working directory. You will have some infos that could help you like which files are in conflict.
It must be one of the other collaborators that updated and pushed a file you just updated. If so, you will have to choose which version you want to keep in your local files.

How can I copy an git repository in Xcode to github?

Every time a try to use github I get tangled in a series of errors that seem to have no solution and I give up. This time I thought I'd try to get help.
I have a local repository created and managed with Xcode. All the local git functions in Xcode work with no problem. Now I want to put this project on github so others can see it. I logged into github and created a repository. It's this one:
lummis/CS193P-2015-Assignment-5
I added a .gitignore file but then deleted it again because I thought it was causing an error. I tried adding a readme file but wasn't able to. I got some error that didn't make sense to me so I gave up on that. So at this point the github repository is empty so far as I can tell.
My local repository has many commits and is currently up-to-date. IOW there is nothing to commit. But when I do "Source Code / Push" I get the following error:
Working copy out of date. Try pulling from the remote to get the
latest changes then push again.
So I try to do that in Xcode by doing "Source Control / Pull". But then I get this error:
"github/master" is not a valid remote branch to pull from. Please
choose a different remote branch.
But there is only one branch. There is no other branch (local or remote) to choose. So I'm stuck in a Xcode-github error loop again. I searched for information about this but didn't find anything relevant. I have the Pro Git book and read and understood it at least thru chapter 2. But that doesn't help on interacting with Xcode.
Can anybody say what I need to do? I thought of deleting the remote repository and starting over but apparently there's no way to do that either!
I know lots of people use github so it must work once you know how to use it but it's a big source of frustration for me.
You have a local repository with "many commits". Let's imagine that we have three:
A---B---C
^
master
Your remote repository on GitHub also contains commits, but they are different ones from what you have locally, e.g.
Y---Z
^
master
At least one of these remote commits was created through the GitHub web interface, which creates a new commit each time you use it.
Because the two repositories contain no common history, Git can't figure out how to handle a push from your local repository to the remote one. It will refuse to accept such a push rather than making any remote commits inaccessible, which is what you usually want.
In this case, commits Y and Z in the remote repository can be discarded. They simply add and then remove a .gitignore file, and you want the remote to reflect what you have locally. The solution is to force push.
Force pushing should generally be avoided, since it can cause commits to be discarded (like Y and Z will be in this case) or to have their hashes changed, which causes major problems with shared repositories. In this instance I don't see any danger in force pushing, which can be accomplished with the -f or --force argument to git push.
(There's nothing fundamentally wrong with force pushing, and in some situations it makes perfect sense, but it should be done with care for the reasons listed above.)

How to undo the sync to get the files in local repo back?

I'm very new to github and I started using it a few weeks ago for my uni group project.
The problem that I'm having is:
There is a remote repo on github where everyone in the group is using.
I do have a local repo on my laptop, where I've worked my part of the project.
I recently committed and synced the updates that I made to github using desktop app for mac.
I got a few errors and the sync failed.
After that when I looked at the files that I have locally, they got overwritten by the ones from the git(non-updated version) and all of my work are gone.
Can you please help me on what I should do to receive the files that I had locally? Is there any way that I can undo that last sync. I found a few suggestions online, but since I'm not sure which one to use, I don't really want to mess up the files anymore.
Thanks
(Nearly) All changes made to git repositories can be undo. We don't know the commands you entered but enter it at Google for a specific solution.
You proberly have to use something like:
$git rebase
