Wine Logger Script with systemd Timer

This page explains how to deploy and use the Wine logging script together with a systemd timer service. The script records information about active wineserver processes, including their prefix, Wine binary, version, and environment variables. It also supports log rotation (keeping only the last 5 logs) and an optional argument to specify a custom log directory.

Prerequisites

A Linux system with systemd.
Wine installed (system Wine, Lutris Wine, Proton, etc.).
Root privileges to install systemd units.
The logging script saved as /usr/local/bin/wine_logger.sh and marked executable:

chmod +x /usr/local/bin/wine_logger.sh

Script Usage

Run manually:

/usr/local/bin/wine_logger.sh [log_folder]

If log_folder is provided, logs are saved there.
If not provided, logs are saved inside each Wine prefix folder.

Create the systemd Service

Create the file /etc/systemd/system/wine-logger.service:

[Unit]
Description=Wine Prefix Logger Service

[Service]
Type=oneshot
ExecStart=/usr/local/bin/wine_logger.sh

This defines the service that runs the script once when triggered.

Create the systemd Timer

Create the file /etc/systemd/system/wine-logger.timer:

[Unit]
Description=Periodic Wine Prefix Logger

[Timer]
OnBootSec=30s
OnUnitActiveSec=60s

[Install]
WantedBy=timers.target

This timer runs the service 30 seconds after boot and then every 60 seconds.

Enable and Start

Reload systemd and enable the timer:

sudo systemctl daemon-reload

sudo systemctl enable --now wine-logger.timer

Verify

Check that the timer is active:

systemctl list-timers | grep wine-logger

View logs generated by the service:

journalctl -u wine-logger.service

Notes

Each run of the script creates a new log file unless one already exists.
Only the last 5 logs are kept per directory; older logs are deleted automatically.
If multiple Wine prefixes are active, one log is created per wineserver process.
You can adjust the timer interval by changing OnUnitActiveSec.
