So you've cloned somebody's repo from github, but now you want to fork it and contribute back. Never fear! | |
Technically, when you fork "origin" should be your fork and "upstream" should be the project you forked; however, if you're willing to break this convention then it's easy. | |
* Off the top of my head * | |
1. Fork their repo on Github | |
2. In your local, add a new remote to your fork; then fetch it, and push your changes up to it | |
git remote add my-fork git@github...my-fork.git |

# Helper script to update the Last modified timestamp of files in a Git SCM | |
# Projects working Copy | |
# | |
# When you clone a Git repository, it sets the timestamp of all the files to the | |
# time when you cloned the repository. | |
# | |
# This becomes a problem when you want the cloned repository, which is part of a | |
# Web application have a proper cacheing mechanism so that it can re-cache files |
Let's have some command-line fun with curl, [jq][1], and the [new GitHub Search API][2].
