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

# determine where your proton binary is, the below assumes default Steam location.
# then update STEAM_ROOT and PROTON_VER

PROTON_ROOT="$HOME/.proton"
PROTON_VER="Proton - Experimental"
STEAM_ROOT="$HOME/.steam/root" # expects: steamapps/common/$PROTON_VER/proton
GAME_ROOT="$(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

Working super nicely. One thing is that you need to set the steam root path to where YOUR PROTON IS, this is usually the default, but if you're like me and moved the library to a dedicated SSD, then you need to change it, and it won't include root, it will just be whatever/mnt/you/have/SteamApps/common/<proton ver>/proton

Appreciate it @khaosdoctor , updated w/ comments
