Why is hard drive is full?

Just a few notes I needed recently to clean up a full Ubuntu hard drive. Find out how much space left on all drives. df -h -T Find recently modified files, this will often point you to the cause of a recently full drive. In this example find files modified in the past 24 hours. By default recursive from current directory. find -mtime -1 Find files of size find / -size +10M -ls I got into a bad habit of used sudo when deleting multiple files. I think because it asked me to confirm, and I didn't look up the man page to see it was as simple as adding either -I or -f (force). So just as a reminder not to use sudo. Delete all files ending in .foo in the current directory. rm -I ./*.foo References: https://help.ubuntu.com/community/find https://www.linux.com/news/hardware/peripherals/8247-disk-usage-analysis-and-cleanup-tools
