I always seem to forget how to solve this problem, and it always starts the same way: me wanting to upload an already existent code to my repository. In case you never did this you should probably follow GitHub’s tutorial first.
Basically the setup is as follows:
$ git init $ git commit -am "Initial commit." $ git remote add origin git firstname.lastname@example.org:your_user/YourProject.git $ git push -u origin master
But sometimes, if you’ve created the repository on GitHub and used their automatic generation of README.md and .gitignore files, you can get this fugly error:
$ git push -u origin master To email@example.com:youruser/YourProject.git ! [rejected] master -> master (non-fast-forward) error: failed to push some refs to 'firstname.lastname@example.org:youruser/YourProject.git' To prevent you from losing history, non-fast-forward updates were rejected Merge the remote changes (e.g. 'git pull') before pushing again. See the 'Note about fast-forwards' section of 'git push --help' for details.
Meaning there is some stuff here that differs with your local repo and I don’t know what the fuck should I do with it.
The solution is simple and I always seem to forget it. You should pull from the remote first, and then push it again. It goes like this:
$ git pull origin master From email@example.com:youruser/YourProject.git * branch master -> FETCHHEAD Merge made by the 'recursive' strategy. .gitignore | 16 ++++++++++++++++ README.md | 4 ++++ 2 files changed, 20 insertions(+), 0 deletions(-) create mode 100644 .gitignore create mode 100644 README.md
$ git push Counting objects: 112, done. Delta compression using up to 8 threads. Compressing objects: 100% (98/98), done. Writing objects: 100% (111/111), 1.03 MiB, done. Total 111 (delta 18), reused 0 (delta 0) To firstname.lastname@example.org:your_user/YourProject.git fcb5a5b..960bd64 master -> master
But beware, following these steps with a GitHub generated .gitignore file would result in the gitignored files being uploaded. Either you download or create your own .gitignore file prior to the first commit, or you delete them manually, like this:
$ git rm --cached filenametodelete
For individual files, or this way:
$ git rm -r --cached directorytodelete/
for directories. Then you should commit and push:
$ git commit -am "Deleted .gitignore files remotely" $ git push
Another problem solved.
