What directory corresponds to Application.persistentDataPath on Linux?

I’m not sure how to find the files I’m writing to in Linux, or see if they exist.

Also, where does the output_log.txt file get written to in Linux? I can’t find it, either.

The logs are written to /home/[username]/.config/unity3d. You could also use the development console along with Debug.LogError to show output on-screen. Anyway printing Application.persistentDataPath results in: /home/[username]/.config/unity3d/[companyname]/[productname]
