每天上班前会所有的代码git pull，保持项目是最新的，但是由于公司使用的架构(thrift微服务)，导致项目特别多，一个项目一个项目的git pull挺麻烦的，于是在想有没有一个好的办法，一次性更新所有的项目。于是在网上搜索发现了git-repo-updater这个小工具。

gitup (the git-repo-updater)

gitup is a tool designed to update a large number of git repositories at once.
It is smart enough to handle multiple remotes, branches, dirty working
directories, and more, hopefully providing a great way to get everything
up-to-date for short periods of internet access between long periods of none.

gitup should work on OS X, Linux, and Windows. You should have the latest
version of git and either Python 2.7 or Python 3 installed.

Installation

With Homebrew:

brew install gitup

From source

First:

git clone git://github.com/earwig/git-repo-updater.git
cd git-repo-updater

Then, to install for everyone:

sudo python setup.py install

…or for just yourself (make sure you have ~/.local/bin in your PATH):

python setup.py install --user

Finally, simply delete the git-repo-updater directory, and you’re done!

Note: If you are using Windows, you may wish to add a macro so you can
invoke gitup in any directory. Note that C:\python27\ refers to the
directory where Python is installed:

DOSKEY gitup=c:\python27\python.exe c:\python27\Scripts\gitup $*

Usage

There are two ways to update repos: you can pass them as command arguments,
or save them as “bookmarks”.

For example:

gitup ~/repos/foo ~/repos/bar ~/repos/baz

will automatically pull to the foo, bar, and baz git repositories.
Additionally, you can just type:

gitup ~/repos

to automatically update all git repositories in that directory.

To add a bookmark (or bookmarks), either of these will work:

gitup --add ~/repos/foo ~/repos/bar ~/repos/baz
gitup --add ~/repos

Then, to update all of your bookmarks, just run gitup without args:

gitup

Delete a bookmark:

gitup --delete ~/repos

View your current bookmarks:

gitup --list

You can mix and match bookmarks and command arguments:

gitup --add ~/repos/foo ~/repos/bar
gitup ~/repos/baz            # update 'baz' only
gitup                        # update 'foo' and 'bar' only
gitup ~/repos/baz --update   # update all three!

Update all git repositories in your current directory:

gitup .

By default, gitup will fetch all remotes in a repository. Pass --current-only
(or -c) to make it fetch only the remote tracked by the current branch.

Also by default, gitup will try to fast-forward all branches that have
upstreams configured. It will always skip branches where this is not possible
(e.g. dirty working directory or a merge/rebase is required). Pass
--fetch-only (or -f) to only fetch remotes.

After fetching, gitup will keep remote-tracking branches that no longer exist
upstream. Pass --prune (or -p) to delete them, or set fetch.prune or
remote.<name>.prune in git config to do this by default.

For a full list of all command arguments and abbreviations:

gitup --help

Finally, all paths can be either absolute (e.g. /path/to/repo) or relative
(e.g. ../my/repo).
