I am following the instructions given here to create a Git repository. All went well until the last line:
$ git push -u origin master
fatal: 'origin' does not appear to be a git repository
fatal: The remote end hung up unexpectedly
I'm using git version 1.7.11.3 on OS X 10.6.8
$ git remote -v
returns nothing
Config file for the repository:
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
ignorecase = true
I've had to open sudoers file using sudo visudo command and add the following to it (under # User privilege specification):
git ALL=(ALL) ALL.
Now if I do:
$ git remote add origin /Volumes/500GB/git-repository/myproject.git
it comes back with no error, but I don't see any code in the repository (it has the aforementioned directories like branches, hooks, ...)
If I do:
$ git push -u origin master
fatal: 'origin' does not appear to be a git repository
fatal: The remote end hung up unexpectedly
$ git remote -v
origin /Volumes/500GB/git-repository/myproject.git (fetch)
origin /Volumes/500GB/git-repository/myproject.git (push)
As it has already been mentioned in che's answer about adding the remote part, which I believe you are still missing.
Regarding your edit for adding remote on your local USB drive. First of all you must have a 'bare repository' if you want your repository to be a shared repository i.e. to be able to push/pull/fetch/merge etc..
To create a bare/shared repository, go to your desired location. In your case:
$ cd /Volumes/500gb/
$ git init --bare myproject.git
See here for more info on creating bare repository
Once you have a bare repository set up in your desired location you can now add it to your working copy as a remote.
$ git remote add origin /Volumes/500gb/myproject.git
And now you can push your changes to your repository
$ git push origin master
