I have this bash command:

find . -type d -mindepth 1 -maxdepth 2 | du -h --threshold=2KB

and I got these results:

r2g: the tarball folders: 8.0K ./cli
r2g: the tarball folders: 24K ./dist/commands/ls
r2g: the tarball folders: 48K ./dist/commands/add
r2g: the tarball folders: 36K ./dist/commands/run
r2g: the tarball folders: 20K ./dist/commands/basic
r2g: the tarball folders: 36K ./dist/commands/config/local
r2g: the tarball folders: 36K ./dist/commands/config/global
r2g: the tarball folders: 92K ./dist/commands/config
r2g: the tarball folders: 4.0K ./dist/commands/find
r2g: the tarball folders: 44K ./dist/commands/init
r2g: the tarball folders: 272K ./dist/commands
r2g: the tarball folders: 416K ./dist
r2g: the tarball folders: 48K ./assets
r2g: the tarball folders: 504K .

but when this command is run by itself:

find . -type d -mindepth 1 -maxdepth 2

I only get this:

r2g: the tarball folders: ./assets
r2g: the tarball folders: ./cli
r2g: the tarball folders: ./dist
r2g: the tarball folders: ./dist/commands

anyone know what's going on? I guess the du command is showing subfolders, of the folders at depth 2, even though find is not explicitly pass them, I guess I have to limit du to a depth somehow?

When the du utility is given a directory pathname, it will, by default, show the size of that directory and all its subdirectories.

When not given a directory (as in your example code), it will show the size of the current directory and all its subdirectories.

You example code will not pass anything to du as the du utility does not read from standard input.

Would you want to calculate the size of each directory, then use

find . -mindepth 1 -maxdepth 2 -type d -exec du -h --threshold=2KB -s ;

Note that this will still include the size of each subdirectory in the calculation since du would recurse by itself, but with -s only the total size is shown.

Would you want to calculate the size of each directory while excluding the size of its subdirectories, then you would have to pass the filenames of the files in the directory to du explicitly. This is a bit difficult to do properly, so I'm not doing that unless it's really needed (a first draft that I attempted ended up calling find from find...)
