GIT Notes: Remote Repositories

GIT Succinctly – free eBook from Synfusion

    Chapter 6 Remote Repositories

Manage connections to other repositories, and list them with,

$ git remote

To get more information about remote repos,

$ git remote -v

Create a new connection to a remote repository,

$ git remote add <user-name> <path-to-repo>

Now you can reach that repo with user-name instead of typing it all out.
Git accepts protocols, file://, ssh://, http//, and git://
example,

$ git remote add <user-name> ssh://git@github.com/<user-name>/<repo-name>.git

Repo can be found at, github.com/user-name/repo-name.git
Delete a remote connection,

$ git remote rm <repo-name>

Remote branches represent a branch is someone else’s repository.
fetching, the act of downloading branches from another repository.

$ git fetch <repo> <branch>

Omit branch if you want all branches in a repository.
View downloaded branches with,

$ git branch -r

Remote branches are prefixed with ‘origin’. You can look at their history with,

$ git checkout

Remote branches behave like read-only branches until you integrate them into your local repository.
Display new updates from ‘origin/master’ not your local ‘master’, like this,

$ git log master..origin/master

You can checkout remote branches but this will put you in a detached HEAD state, and without a branch changes will be lost, unless you create a new local branch tip to reference them.

Incorporate changes from origin/master into a local branch,

$ git checkout <mybranch>
$ git fetch origin
$ git merge origin/master

This results in a “3-way” merge. Your master has merged with origin/master and that then merges with your branch. This will produce many meaningless merge commits.
This can be overcome with rebasing,

$ git checkout <mybranch>
$ git fetch origin
$ git rebase origin/master

‘pull’ is the ‘fetch/merge’ sequence combined.
Fetch the origin’s master branch and merge it into the current branch.

$ git pull origin/master

That will merge, but if you’d prefer to rebase use the ‘–rebase’ flag, which I think would be used like this,

$ git pull --rebase origin/master (not certain that’s where the flag goes in this command)

Send local branch to a remote repository,

$ git push <remote> <branch>

This creates a local branch on the remote repository. (So a local branch can appear on a remote repository if someone remotely pushes to it. I think!!!)

Public repositories are bare repositories, they do not have working directory.

Create a bare repository with,

$ git init --bare <path>.git

Bare repositories only function as storage facilities.

A push to a origin/master may be aborted because your local branch is not in sync.
Synchronise with a central repository,

$ git fetch origin master
$ git rebase origin/master
$ git push origin master
