Forked from the great web console project, and turned into a silverstripe CMS project.
composer require isobar-nz/web-console ^2.1
It acts like a simple SSH shell, but in a CMS admin panel.
Useful for web hosts that give you shared or web-only access, but no ssh or other console.
Unfortunately you don't get any interactive shell functionality (e.g. nano), but you can do most single line commands.
Typically commands will be sent to the server, be triggered, and return the result once it's completed.
If you have a long running task, then instead you should use 'stream' command to stream the task in the background. When using this command, the task will be run in a separate process, and the frontend javascript will poll the server for output (don't refresh the page while this is running though!).
run stream --help in the console for help.
Note: You don't need to install crontask, as webconsole has it's own process control based on Symfony.
