This tool does not provide a centralised way of managing your games or utilise template umu-configs. See faugus-launcher or Nero-umu for something more akin to a games launcher, and umu-wrapper for templating functionality.
Proton versions can track and untrack game configs, with the intention of safely removing them once no config (and subsequently application) depends on one.
Vanilla umu config files currently (06/2025) do not support setting environmental variables or runners. This tool adds such functionality with an extra TOML table within said configs, see example_config.toml for an example.
The configuration file lives at ~/.config/umu-commander.toml, which cannot be changed as of now. You can generate one by running the app by itself.
The config schema is as follows:
| Name | Description |
|---|---|
DB_DIR |
Directory where the Tracking DB is stored. |
DB_NAME |
Tracking DB filename. |
DEFAULT_PREFIX_DIR |
Directory where umu-commander will search for WINE prefixes. |
PROTON_PATHS |
List of directories umu-commander will search for Proton versions. |
DEFAULT_UMU_CONFIG_NAME |
Default name of the umu config created using umu-commander create. |
UMU_PROTON_PATH |
Directory where umu-launcher downloads its UMU-Proton versions. |
[DLL_OVERRIDES_OPTIONS] |
TOML table where all possible DLL overrides are listed. |
[LANG_OVERRIDES_OPTIONS] |
TOML table where all possible LANG overrides are listed. |
To add an extra DLL override option, add a line below the table in the form "Label" = "WINE DLL override string". Use the winhttp example as an example. You can add LANG overrides in a similar way.
umu-commander needs one of the following verbs specified after the executable name:
| Name | Description |
|---|---|
track |
Tracks selected config with the selected Proton version. Also removes it from any other tracking lists. |
untrack |
Removes the selected config from all tracking lists. |
users |
Lists which configs the selected Proton version is tracking. |
delete |
Interactively deletes Proton versions that are currently tracking nothing. Will not remove the latest UMU-Proton and Proton versions that haven't been used for tracking before. umu-commander will never delete anything without invoking this verb and confirming. |
create |
Creates an augmented umu config in the current directory. These configs are compatible with vanilla umu-launcher, although the DLL override functionality won't work. |
run |
Runs a program using the umu config selected. |
fix |
Attempts to fix invalid paths created from moving configs around. |
Add umu-run to your PATH and then install with pipx by running pipx install umu-commander.
After that you can run umu-commander -h for an explanation of the options, and umu-commander <verb> [<options>] for using the app's functionality.
| Number | Name | Description |
|---|---|---|
| 0 | SUCCESS |

| 1 | DECODING_ERROR |
Failed to parse a file. |
| 2 | INVALID_SELECTION |
User selected an invalid verb or there are no valid selections. |
