# Launches satisfactory and syncs savefiles to S3 storage on exit

# Put this script anywhere you like such as ~/.local/bin/
# Make sure to make it executable with `chmod +x sync_saves.sh`

# You need to create an S3 bucket named satisfactory
# For exemple, you can use https://filebase.com/

# You need s3cmd to be installed and configured:
#   Installation:
#     From the AUR: https://aur.archlinux.org/packages/s3cmd-git
#     Otherwise, manual installation:
#       wget https://github.com/s3tools/s3cmd/releases/download/v2.2.0/s3cmd-2.2.0.tar.gz
#       tar -xzvf s3cmd-2.2.0.tar.gz
#       cd s3cmd-2.2.0
#       sudo python3 ./setup.py install
#   Configuration:
#     Read https://docs.filebase.com/third-party-tools-and-clients/cli-tools/bash/backup-files-to-ipfs-with-bash#3.-next-configure-s3cmd-for-use-with-filebase

# Finally, to run the script:
# Launch the game as `<PATH_TO_SCRIPT> <WINEPREFIX> %command%`
# Prefix folder is the folder that contains `pfx`
# On steam:
#   Put the command in the launch arguments
#   Prefix is: `<STEAMFOLDER>/steamapps/compatdata/<APPID>`
