The short: is there a way to have a git repo push to and pull from a list of remote repos (rather than a single "origin")?

The long: I often have a situation when I'm developing an app in multiple computers, with different connectivity – say a laptop while on transit, a computer "A" while I'm in a certain location, and another computer "B" while on another. Also, the laptop might have connectivity with only either "A" or "B", and sometimes both.

What I would like to is for git to always "pull" from and "push" to all the computers it can currently connect to, so it's easier to jump from one machine to the other and continue working seamlessly.

Doing this manually is no longer necessary, with modern versions of git! See Malvineous's solution, below.

Reproduced here:

git remote set-url origin --push --add <a remote>
git remote set-url origin --push --add <another remote>

Original answer:

This something I’ve been using for quite a while without bad consequences and suggested by Linus Torvalds on the git mailing list.

araqnid’s solution is the proper one for bringing code into your repository… but when you, like me, have multiple equivalent authoritative upstreams (I keep some of my more critical projects cloned to both a private upstream, GitHub, and Codaset), it can be a pain to push changes to each one, every day.

Long story short, git remote add all of your remotes individually… and then git config -e and add a merged‐remote. Assuming you have this repository config:

[remote "GitHub"]
    url = [email protected]:elliottcable/Paws.o.git
    fetch = +refs/heads/*:refs/remotes/GitHub/*
[branch "Master"]
    remote = GitHub
    merge = refs/heads/Master
[remote "Codaset"]
    url = [email protected]:elliottcable/paws-o.git
    fetch = +refs/heads/*:refs/remotes/Codaset/*
[remote "Paws"]
    url = [email protected]:Paws/Paws.o.git
    fetch = +refs/heads/*:refs/remotes/Paws/*

… to create a merged‐remote for "Paws" and "Codaset", I can add the following after all of those:

[remote "Origin"]
    url = [email protected]:Paws/Paws.o.git
    url = [email protected]:elliottcable/paws-o.git

Once I’ve done this, when I git push Origin Master, it will push to both Paws/Master and Codaset/Master sequentially, making life a little easier.
