If you need to find the amount of disk space being consumed in Linux, you can show it recursively through your directories as follows.

$ sudo du -ahx /var | sort -rh | head -10
357M /var
250M /var/lib
185M /var/lib/rpm
177M /var/lib/rpm/Packages
79M /var/cache/dnf
79M /var/cache
34M /var/lib/sss
29M /var/log
27M /var/lib/sss/mc
27M /var/lib/selinux/targeted/active

Mac/Unix systems can use the following command.

% sudo du -sk /Volumes/HD2/Installers/* | sort -rn | head -10
69298256 /Volumes/HD2/Installers/ISO
602508 /Volumes/HD2/Installers/Adobe-DNG-Converter
405012 /Volumes/HD2/Installers/VMware vSphere Hypervisor ESXi 7.0U3d
81728 /Volumes/HD2/Installers/Keychron-keyboard
68540 /Volumes/HD2/Installers/Luminar
59848 /Volumes/HD2/Installers/Iperius-Backup
55888 /Volumes/HD2/Installers/iStat Menus.app
42424 /Volumes/HD2/Installers/WP-Dupe
24048 /Volumes/HD2/Installers/istatmenus6.31.zip
156 /Volumes/HD2/Installers/Bandwidth-Tester

These commands will show the disk usage in order, highest amount of space first in the directory specified.
