Grid5000-code is a repository of user-contributed scripts and tools that aim at improving the daily life of Grid'5000 users, by making the platform easier to use.

The scripts are distributed automatically on all Grid'5000 frontends, in /grid5000/code. The scripts are divided in two categories:

  • public scripts: located in the bin/ subdirectory, that is also part of the default $PATH. Those scripts are considered good enough for everybody to try and use them.
  • 'tentative' scripts, located in the staging/ subdirectory. While you might find very interesting scripts in this directory, there is no guarantee about the quality of this software.

For more information about the various scripts, see bin/README and staging/README.

Everybody is strongly encouraged to contribute new scripts and improve existing scripts. The scripts are hosted in the grid5000-code SVN repository on See for more info. Note that the technical team doesn't provide support for those tools.

When are the scripts replicated to Grid'5000?

The scripts in staging/ are automatically replicated to Grid'5000 frontends when someone (you?) execute g5kcode-update.

The scripts in bin/ are replicated to Grid'5000 on an on-demand basis, when a release is decided.

Follow the instructions on

How do I contribute a new script?

Commit it to the staging/ directory. Follow a sane naming convention, and include in the script:

  • a summary of what the script does
  • contact information (with email address, institution information)
  • a copyright and license statement (you might want to copy it from other scripts, like bin/katapult)

What about licensing and copyright?

Each script can have its own copyright and license. However, it is strongly recommended that you choose a common Free Software license for your script.

If no licensing information is provided on a script committed to SVN, It is assumed that the script is distributed under the terms of the GNU General Public License, version 2, or any later version.

How do I improve an existing script?

Normal behaviour rules apply: you should contact the script's author, and ask him if he/she is interested in integrating your changes, or ask for the permission to commit them yourself. In the meantime, you can temporarily "fork" the original script, by renaming it.

How do I move the script from staging/ to bin/?

Contact the mailing list ( and ask for an informal review. Please make sure that your script is in a good state before starting the process. In particular, make sure that its behaviour towards the platform is sane (do not DOS OAR, for example), and that it provides enough documentation (through a --help option, for example) for everybody to be able to use it.

How do I make a file executable?

Execute the following command on the script:

svn propset svn:executable <script>
