easily run an .exe with proton on linux

proton

#!/usr/bin/env bash

# This script launches a Windows executable using Proton within a Linux environment.
# It requires exactly one argument: the path to the executable to run.
# It sets up a separate Proton prefix for each executable to avoid conflicts.
# Usage: proton <path-to-executable>

if [ "$#" -ne 1 ]; then
    echo "Usage: $0 <executable-path>"
    exit 1
fi

PROTON_ROOT="$HOME/.proton"
STEAM_ROOT="$HOME/.steam/root"
PROTON_VER="Proton - Experimental"
GAME_ROOT="$(dirname "$1")"
GAME="$(basename "$1")"

cd "$GAME_ROOT" || exit

mkdir -p "$PROTON_ROOT/$GAME"
export STEAM_COMPAT_DATA_PATH="$PROTON_ROOT/$GAME"
export STEAM_COMPAT_CLIENT_INSTALL_PATH="$STEAM_ROOT"

"$STEAM_ROOT/steamapps/common/$PROTON_VER/proton" run "$1" >/dev/null 2>&1

I got here from google- this still works, thank you!

I just want to say that this works like a charm!

In case it does break in the future, it will most likely be due to the hardcoded Proton - Experimental variable (e.g. due to name changes).

If the script does not work for you, paste the following command in the terminal and replace the value of PROTON_VER with your preferred Proton version:

ls -1 ~/.steam/root/steamapps/common/ | grep 'Proton'
