How to download files from lilina to your PC

1. If you are using Mac OS, Windows 10 or Windows 11, this is quite straightforward. These operating systems have a built-in "scp" program for you to securely copy files from/to a remote server.
2. In Windows 10/11, start a command window:
   
3. Change to a directory which you usually download files.
   
4. Run the command "scp lilina.csie.ncnu.edu.tw:hw01.cpp .", assuming you want to download the file "hw01.cpp" from lilina to your PC.
   
5. If this is the first time you connect to that server, you will be required to confirm whether you are sure to connect, by typing "yes", and press ENTER.
   • On Windows 10, while you are typing "yes", these characters may not be displayed. Just type them and press ENTER.
   • Windows keeps a list of servers that you have connected in C:\Users\username\.ssh\known_hosts, while Mac OS keeps that in ~/.ssh/known_hosts.
6. After that, you will be prompted to type your password on lilina.
7. The file will be successfully downloaded into C:\Users\username\Downloads.
