I'm attempting to install a new app on an Ubuntu 18.04 system. I want to redirect the files outputted to a USB drive, rather than on my SSD.

eg:

 /var/snap/sabnzbd/common/Downloads/incomplete

to

 31 gb /Downloads/incomplete

(where 31 GB) is the ubuntu assigned name of the USB drive.

I KNOW this MUST be awfully silly sounding question, but I am a TOTAL nube

In this specific case the easiest solution is likely to modify a configuration option in the SABnzb program you're using:

https://sabnzbd.org/wiki/configuration/2.3/folders

These configuration changes make the program write it's files in different places, such as your USB drive.

But, what if a program doesn't have a configuration option like that? In that case you would either mount or link part of the filesystem to a different part of the file system:

  • Mounting involves taking a device (such as a USB drive) and placing it's contents somewhere into the file system. For example, your root file system / is mounted from your SSD device currently. If you wished you could modify the /etc/fstab to have your USB device mounted to /var/snap/sabnzbd/common or similar.

  • Linking involves using the ln utility to link one area of the drive to another. In this case your USB device is likely already mounted to /media/something and you can create a symbolic link (called a symlink or sometimes called a "soft" link) from one part of it to another. In this case you would make a directory inside your USB drive then link it to /var/snap/sabnzbd/common or similar. Note, you would first probably want to copy that information to the USB drive. See this if you're interested in the differences between "soft" and "hard" links.
