问题
Is it possible to cd to my desktop when using the terminal in Cloud 9 for Rails environment?
If not any folder on my local Hard Drive would be fine.
回答1:
There is no built-in way to sync the code in your cloud9 workspace with your desktop machine.
But you have several ways to copy files from and to your cloud9 workspace.
1. Git/Github
You can use git and github (or any other distributed revision control system) to sync your code (i.e. Upload (git push) your code from cloud9 and later download (git clone) to your desktop machine).
2. Download from Cloud9
Rigth-click on the file or folder in the Workspace tree (on the left of your cloud9 workspace) and select Download.
3. Upload from your local machine
Drag-and-drop you local file to a specific folder on your Workspace tree.
