Names in Git
Reference
References available in a remote repository can be listed with git ls-remote.
Refspec
URL
Local Repository
The repository maintained on a local filesystem that is currently interacted with is called the local or current repository.
Remote Repository
A repository maintained on a remote host, but with which files are exchanged, is called a remote repository. The references available in a remote repository can be listed with git ls-remote.
Remote
A remote is named entity whose definition is maintained in .git/config that represents a reference to a remote repository. The remote can be seen as a short name for a long URL and other configuration information.
[remote "origin"]
url = git@github.com:NovaOrdis/events-api.git
fetch = +refs/heads/*:refs/remotes/origin/*
The 'url' is the URL of the remote repository. 'fetch' is a refspec that specifies how a local ref (which usually represents a branch) is mapped from the namespace of the source repository into the namespace of our repository. The content of these branches will be transferred when [git fetch#Internals] is executed. For more on refspecs, see [NamesInGit#Refspecs]. Instead of specifying * that signifies all branches, you can list individual branches there:
{{{
...
fetch = +refs/heads/dev:refs/remotes/origin/dev
fetch = +refs/heads/stable:refs/remotes/origin/stable
...
}}}
These definitions can be manipulated with [git config#RemoteManipulation].
The remote is used in assembling the full name for the [tracking branches|GitConcepts#TrackingBranch], also declared in .git/config.
Remotes can be created, removed and manipulated with [git remote].
!Origin
The "origin" is a special remote that refers to the repository the current repository was cloned from. The name "origin" is just a default value and it can be changed if so desired with --origin option of the [git clone] operation.
