I like this command which I often use to look into the dish usages at the sub folder level to check for large usages

du -h -d 1
1.3M    ./Espresso-BEEF
65M     ./MATLAB
478M    ./Abaqus
10G     ./COMSOL
8.3M    ./Gaussian2
316K    ./scripts
4.9M    ./NB07
647M    ./pytorch-GAN
31M     ./Gaussian
12G     .

where

• -h refers to human-readable
• -d refers to depth level. By default, it is 0 which is the same as summarize
