When working with a remote server you will need to transfer files to and from the server. You can either do this with a GUI client such as filezilla or fugu or you can do it with the commandline tool scp.
If you are planning to work from an external network (e.g. from home) then fugu is the only GUI software that can help you (and it's only available for mac), however scp will work from any network/platform.
The syntax of scp is very similar to that of cp (to copy files). It follow the general pattern
scp files_to_transfer new_location
This can be read as "I want to copy (scp) these files (file_to_transfer) to a new location (new_location)"
Home to server
So for example, if you have a file called data.txt on your laptop and you want to copy it to the server (ip address: 10.18.0.11, username: jody) then you can do the following.
Note how the 3rd parameter is just a dot. This is a special variable in bash which meant he current location. So the file will be transferred to the folder you are currently in.
If your files on the server are in a sub-folder (e.g. beast/data.txt) then you can just add that to the remote file descriptor. You can also transfer into a different folder on your own computer (e.g. ~/Documents).
