The repo tool is a source code configuration management tool used by the Android project. The repo tool is a front end to git written in Python. It uses a manifest file to help download code organized as a set of projects that are stored in different git repositories.

To install repo, do the following:

1. Create a ~/bin directory in your home directory, or, if you have root or pseudo access, install for all system users under a common location, such as /usr/local/bin or somewhere under /opt.
2. Download the repo script.

$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo

3. Set the repo script attributes to executable.

$ chmod a+x ~/bin/repo

4. Include the installed directory location for repo in your PATH.

$ export PATH=~/bin:$PATH

5. Run repo –help to verify the installation.

$ repo –help

You should see a message similar to the following:

usage: repo COMMAND [ARGS]

repo is not yet installed. Use “repo init” to install it here.

The most commonly used repo commands are as follows:

init -> Install repo in the current working directory

help -> Display detailed help on a command

NOTE: For access to the full online help, install repo (repo init).
