rsync

rsync [options] <source> <destination>

Synchronizes destination with source where either of them can be remote, not both.

rsync -aPL sandbox:/Work/project/ ./project

It downloads file from remote location project/ and stores them in location ./project.

sandbox:/Work/project/ ends with / that will download the file inside the directory. If the path would be like sandbox:/Work/project, it will copy the directory itself into destination.
