In the terminal, copy files using scp to download files from Transit:

where [remote_filename] is the path to a remote filename, [username] is your UPPMAX username, and [local_folder] is your local folder, for example:

scp sven@transit.uppmax.uu.se:/home/sven/my_remote_file.txt /home/sven

This is how you would copy a file from your local computer to Transit:
