Clear Steam Achievements (Linux)

A tiny command-line application to clear all achievements for a game on Steam, on Linux.

For some games I like to clear all achievements before playing the game again, so I can once again earn all the achievements in the game.

I used to use Steam Achievement Manager for that on Windows. I wasn't able to get that working on Linux, which is why I wrote this application.

Note that 80% of the code was generated by Claude, but it wasn't working. I fixed the code, cleaned it up, and refactored it.

⚠️ WARNING ⚠️ Do not use this on on-line games or games using anti-cheat, as there are some reports that people can get banned in such games for using these kinds of tools. It should be safe to use on single-player games. I've been using Steam Achievement Manager for this with single-player games for years without issues.

Usage

./clear-steam-achievements <steam_app_id>

To get a Steam App ID, right-click on a game in your library, click Properties, and go to Updates. Alternatively, go to the store page and copy-paste the ID from the URL. E.g. for The Witcher 3, the App ID is 292030.

Make sure that the Steam client is running and that you own the game.
