Organist Terminal

Organist Terminal (organist-term) is written in node.js and can be used in any web application where you need a real-time terminal in the browser to monitor execution of some shell command. Typical workflow would be to ask the user for some parameters, which will result in a command that is stored in MySQL after which the user will be redirected to the exection page which will show the realtime exection.

Its use case is very specific for the Organist deployment tool, but should be usable on its own.

Key Features

• Read only terminal, except for the Ctrl-C signal which will abort execution
• Command provisioned from MySQL
• Output log is stored in MySQL
• Multiple monitoring instances supported (multiple users can view same execution)

Installation
