How two laptops can git push/pull to each other with no internet

Question

Say my co-hacker and I find ourselves on a desert island. Normally we push and pull to github to sync with each other. How would you recommend we do so when we have no conne

Answer 1

One solution compatible with your scenario would be to share through an USB stick one file through git bundle

That allows you to:

• consider that one file (the 'bundle') as an upstream repo to which each user can update said bundle, and from which they can fetch new commits.
• avoid trying to synchronize a large collection of files/meta data within a bare repo structure.
• don't rely on any network/server process whatsoever.

Answer 2

Take a SD-Card, or an USB-stick or something. Create a bare repository there. Then one push to that repo, unmount the card/stick, give it to the other, that one pull from it.

cd /path/to/usbstick
mkdir repo
cd repo
git init --bare
cd /path/to/local/repo
git remote add usb /path/to/usbstick/repo
git push usb --all

One the other machine

cd /pat/to/local/repo
git remote add usb /path/to/usbstick/repo
git fetch usb --all

Answer 3

For starters - get this book - http://book.git-scm.com/

Second, there is a section on page 40 titled Distributed Workflows

That should cover what you need, just use ssh as your comms protocol (assuming you're familiar with ssh from command line)

Answer 4

Running a git server locally should work if you're on the same network. One would push to his own machine, the other to the other machine (based on local IP).

Answer 5

The simplest solution is probably to just set up an ad-hoc wireless and SSH to eachother's laptops. You can set up your remote with

$ git remote add cohacker myuser@cohackers-laptop:/path/to/repo.git

Now you can push/pull to your heart's content:

$ git pull cohacker master
 ... hack away ...
$ git push cohacker master
