Copy Files
cubic scp copies files and directories between the host and a VM instance,
and between two VM instances. Both VM instances have to be running, because
cubic scp does not start them for you.
Upload a File
$ cubic scp ./notes.txt demo:~/
Check that the file arrived:
$ cubic exec demo "cat ~/notes.txt"
hello from the host
Download a File
$ cubic scp demo:~/result.txt ./result.txt
$ cat ./result.txt
made in the guest
Copy a Directory
$ cubic scp demo:~/Downloads .
Copy between Two VM Instances
$ cubic scp demo:~/result.txt other:~/
A path is a guest path when it carries an instance name in front of the colon and a host path when it does not, so the two arguments decide the direction of the copy.
