m4cs/targkill

targkill is a command-line tool for Rust developers that finds every target/ build folder on your system and shows you how much space each one is using. When you build Rust projects, the compiler stores compiled artifacts in a folder called target/. These folders can grow to several gigabytes per project and are safe to delete at any time since Cargo regenerates them on the next build. targkill makes it easy to find them all and reclaim the space. You install it with cargo install targkill, which adds it as a Cargo subcommand. Running cargo targkill opens a terminal interface that scans your home directory (or a folder you specify) and lists every Cargo target folder it finds with its size. Sizes appear as they are calculated, so you do not have to wait for the full scan before seeing results. The list highlights any folder over one gigabyte so the largest ones are immediately visible. The tool is careful about what it includes: it only lists a target/ folder if a Cargo.toml file exists next to it. A folder named target/ for another reason is ignored. This keeps the results accurate and avoids touching unrelated directories. In the terminal interface, you navigate with arrow keys or vim-style j/k keys, toggle individual items with Space, select or deselect everything, sort by size, name, or age, and delete the selection. Deletions are permanent with no recycle bin, but a confirmation prompt appears before anything is removed. Deletions run in the background so the interface stays responsive even when removing large folders. A --list option prints results as plain text for use in scripts. The tool runs on Linux, macOS, and Windows.
