Protonsh

Simple shell tool to ease operations inside Proton prefixes.

Usage

The script currently takes no arguments. When run, it will:

1. ask the user on which Proton prefix he wants to operate;
2. ask the user the desired Proton version to use.

After this, a number of environment variable overrides will be performed to ensure that any wine-specific tooling will work on the selected Proton prefix, using the selected Proton version executables (wine/wine64 will indeed point to the selected Proton version binaries).

Steam library directories location

All the prompts previously described are based on locating the Steam library directories (SteamApps/steamapps) and looking at their contents. This is done by looking at the default ~/.steam/steam/steamapps location and at the directories pointed at by the BaseInstallFolder settings inside the config.vdf file.

Local overrides

Local environment variable overrides can be specified in the ~/.config/protonsh file, that will be sourced if found.

These are the available variable overrides:

Variable name	Description	Default value
STEAMAPPS_DIRS	Steam library directories location. Must be an array	Autodetected
SHELL	the shell to launch inside a Proton prefix	/bin/bash
LOGLEVEL	the log level of log messages. Can be ERROR, WARN, INFO, DEBUG	WARN

Installation

There is a basic Makefile in place to ease installing the script on the system.

Run make or make help to see what commands/variables are currently supported.

By issuing a make install command as root, the script will be put in /usr/bin/protonsh. If you'd like to change the installation prefix to something other than /usr, you can override this by overriding the PREFIX make variable, like:

make PREFIX=/usr/local install

To ease package creation, the DESTDIR make variable is used throughout the Makefile as a prefix to PREFIX ;-)
