what is winetop fr?

winetop is a command line tool for Linux that shows you what is running inside Wine, the compatibility layer that lets Windows programs and games run on Linux. If you have used htop to watch which processes are eating your CPU, winetop does the same thing but understands Wine specifically, along with the tools built on top of it like Proton (used by Steam), Lutris, Heroic, and Bottles. Instead of a flat list of confusing process names, it groups everything by the actual game or app session it belongs to, so you can see at a glance which Steam game or launcher is using how much CPU and memory. The tool works both as an interactive full screen text interface and as a plain command line utility you can script. In the interactive mode you can expand a session to see its individual processes, view live CPU and memory graphs, and kill a stuck session safely: winetop tries a gentle stop signal first, then falls back to Wine's own shutdown mechanism, and only forces a hard kill as a last resort, so it avoids accidentally killing your entire Steam client along with one game. From the command line you can list sessions, print a tree view, dump a JSON snapshot, find orphaned processes, or kill a specific session by its Steam app ID, its Wine prefix path, or its process ID. winetop can also feed live status information to status bar tools like Waybar, useful if you want a quick CPU or memory readout for the game currently running in your system tray area. It figures out human readable names for what it finds by reading metadata files that Steam, Lutris, Heroic, and Bottles already keep on disk. Installation is available through several Linux package managers including apt via a PPA, Fedora's Copr, the Arch User Repository, Homebrew, Nix, and Rust's own Cargo package manager, or by downloading a prebuilt binary from the project's GitHub releases page. It is written in Rust and released under the MIT license.
