CODESH

"COllaborative DEvelopment SHell is an intelligent shell, which automatically logs a user's command line (shell) session: commands, scripts executed, output produced, changes to environment variables, alias creation and other information needed to recreate the session later. This session is uniquely tagged and stored in local or distributed backend repositories and can be extracted and reproduced at any time by the user who created the session or by collaborators located anywhere in the world.

The fundamental concept in CODESH is to store all the information necessary to reproduce a user's session. This is achieved by maintaining a virtual logbook, which records the initial state (pre-conditions of a session), all the commands typed by the user, all the outputs generated and also all the programs (shell scripts) executed to produce the results. Also the changes made to the environment i.e. environment variables and aliases are recorded. When a user's session ends, or even before, if the user so desires, CODESH tags the complete log along with the data and source program files with a uniquely generated tag and logs it to a repository. The repositories can contain hundreds and thousands of such stored sessions.

Reproduction of a session is possible by extracting the log, data and source files, and executing the commands listed in the log files including running the scripts that are downloaded from the repository in their original form as when the session was recorded. Later changes or even deletion of scripts have no effect on the reproducibility of sessions as the scripts can be retrieved from the repository anytime.

Also the environment changes can be carried across sessions. The repositories of such sessions can be on the local machine for personal usage or on shared servers for the use of collaborating groups. Generally the user will store all his sessions locally and 'publish' a few important sessions to some shared repository. He may also extract and reproduce stored sessions of other collaborators."
