Fixes a common Proton/Linux specific issue with Gray Zone Warfare not launching with an EAC error after update.

How it do that

chmod 444 /path/to/2/.dat/files/that/need/to\ be/read-only

How to run it

1. Download source or git clone https://github.com/devmapall98/fix_gzw_eac/
2. Open the downloaded folder
3. Add execute permissions to script with chmod u+x ./fix_gzw_eac.sh
4. Run it with ./fix_gzw_eac.sh
5. Profit

On first run it will create and populate a default config. If your game is installed outside of the default Steam games directory go ahead and edit the newly create .conf file and change the path manually.

You can use this manually each time GZW updates (before launching the game, otherwise you will be forced to verify game files first) or set it to run on game launch via Steam launch args.
