The motivation of this project is for me to learn Rust. After reading half of two different books, I wrote ds. The program is useful but primitive. My next goals are further exploring unit tests and command line arguments.
Linux users are familiar with the df and du commands, respectively disk free and disk usage. When a filesystem is full (or nearly so), df will confirm that available space is zero. The du command with options can be more helpful. For example,
du -sm * | sort -n
will list all files and directories. However, hidden files and directories are not included. Using
du -sm .??* *| sort -n
will include hidden files and directories without including the parent directory. Additionally, knowing the largest directory simply means traversing any of the subdirectories and repeating the command. Tracking down the largest directories and files allows one to make the decision to remove them or accept that more space is necessary.
Explaining the above to new Linux users such as how shell expansion works, that directories such as .a will be skipped and the large numbers are all mebibytes will be unwelcome. For experienced users, the investigation is a distraction and takes too long.
The program ds returns the 20 largest directories and files from the current directory. The output is human friendly with appropriate units. For example, the output of the src directory is
14M ./target/debug
14M ./target/debug/deps
7M ./target/debug/deps/ds-6f1846660d97a074

This command can help find old browser cache files, a misplaced ISO image or a sudden increase in assets of a game.
Since this is Rust, the command is
$ cargo build
