I have a primary SSD with all my stuff and a 2nd hard drive where I install my games. The SSD has a 120 GB capacity. Until recently, only ~20GB has been used, but something has happened and now 87GB is being used.

How do I determine what's occupying the space?

Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        4.0M     0  4.0M   0% /dev
tmpfs           3.9G   17M  3.9G   1% /dev/shm
tmpfs           1.6G  9.8M  1.6G   1% /run
/dev/sda1       112G   81G   30G  73% /
tmpfs           3.9G  3.9M  3.9G   1% /tmp
/dev/sda1       112G   81G   30G  73% /.snapshots
/dev/sda1       112G   81G   30G  73% /home
/dev/sda1       112G   81G   30G  73% /root
/dev/sda1       112G   81G   30G  73% /var
tmpfs           792M  188K  791M   1% /run/user/1000

bottom of: du -m / | sort -n | tail -88:

5292    /home/marko/.local/share/Steam
5652    /var
7099    /home/marko/.local
7099    /home/marko/.local/share
14065   /home
14065   /home/marko
192422  /.snapshots
216810  /

    I'm sure this has been answered before. I'll try to find you a reference. Upshot is that df shows how is used on the filesystem according to the filesystem itself. du works through the directory tree looking for files. There's a bunch of reasons files may not be visible from corruption through to simply having an open file that's already been deleted.

On the command-line, enter

ls -lhR > test.txt

That will print the output of the command to the file test.txt.

You can then open that file and read through it at your leisure.

So I take it that the /dev/sda1 is your 'primary' drive.

I wonder why you have it mounted so many times (five, by my count)? In terms of finding out what's taking up the space, simply run ls -lhR for a list of all the files and the size of each file, including subdirectories.

You can put it all in a txt file by running the command with a > text.txt after it.
