I want a unix/linux tool that runs through a directory tree, finds all the cargo `target`, npm `node_modules` and go `whatever go uses` directories, tells you how much disk space they're taking up, and then optionally deletes them. I could easily write such a tool myself but I'd be afraid of like accidentally deleting some directories named "target".

Does this exist. I remember someone talking about this but I don't remember if they found one or just were wishing for it out loud.
