FYI this script does not account for the following scenarios:

1. If your games are stored on another drive, as in outside your home folder. I myself have two additional storage drives mounted elsewhere, since well, games are big and need to put them different places.
2. Once adapted to other locations, this script is also intolerant for spaces in parent folders where a Steam Library could be housed at. Like "/mnt/ssd-1tb/Steam Library" kind of deal.

I'm not sure what the best solution to #1 is, however for #2, double quotes are needed to surround the variables in the early parts declaring paths and sub-paths, and then also for the cd $dir step, should be cd "$dir", and the replace_dlls step needs double quotes around both 32 and 64 bit dirs.

The double quotes may be needed for arch too, but I could be wrong there.

I had to manually adapt the script for my situation and hopefully this helps someone else in the future.

Either way though, thanks for this script! \o/

For the people who have steam installed by snap, change:

STEAM_DIR=/home/$USER/.steam/steam/steamapps

to:

STEAM_DIR=/home/$USER/snap/steam/common/.local/share/Steam/steamapps

After this script with GE Proton still had the sync issue, it let me get an hour into the match before that tho. I was able to play through shorter matches no problem.

I've modified this to be a generic version of this to work with most other games by passing the APP ID. Also collected some additional examples for users so they don't have to edit the file directly (they still can though)
