# (clientappid) decides which client can connect: 4465480 for standalone CS:GO, 730 for the CS2 csgo_legacy branch.
# SteamCMD update/validate can revert these files, so this runs before every start.

# Fixes: server not always creating steam_appid.txt file.
# The server writes steam_appid.txt with a trailing null byte, which is removed before comparing.
