Backup your files!
rsync -a -v /home/student <username>@access.scs.carleton.ca:COMP3000/
Become root (so you can delete anything)
sudo su -
Check how much free space you have in your current directory (human readable):
df -h .
Find out which files/directories are taking up too much space
du -x / | sort -nr | head
Delete files
rm <file> rm -rf <directory> # -f means force, so be sure you specify the right directory!
Clean logs (you may need to reboot to empty out active log files)
rm /var/log/<large log file> journalctl --vacuum-size=1M # keep only one megabyte of logs
