SteamCMDでサーバーのアップデートをチェックする
サーバーのアップデートを知りたい
Steamで販売されているマルチゲーの中には7d2dやCSシリーズなど自分で専用サーバーを構築し、友人と遊べるものがいくつかあります。
そういったものはSteamCMDというツールを用いてSteamからサーバーのデータをダウンロードすることができます。
24時間サーバーを運用していると、自動でアップデートをしたいなということがあります。
アップデート自体はインストール時と同じコマンドを使用すればいいので、楽なのですが、
問題はアップデートを発火する際のアップデート検知をどうするかということです。
SteamCMDを用いることでアップデート検知っぽいことができるため、書き残しておきます。
ローカルのビルド番号
+app_statusという引数を使用することで、ローカルの情報を手に入れることができます。
BuildIDがバージョン毎に一意っぽそうなので、これを使用します。

なので、以下のコマンドでビルド番号だけ手に入れれますね。

リモートのビルド番号
+app_info_printを使用することで、リモートの情報を手に入れることができます。
返り値はjsonっぽいのですが、標準出力にsteamcmdのログ自体も出ちゃうのでそのままjqなどには渡せそうにもなさそうです。

比較
あとは一定時間ごとに返り値同士を比較して等しくなければ(もしくはリモートが大きければ)アップデートを走らせる。という処理を書いてあげたらよさそうですね。

まとめ
SteamCMD君json投げるか普通に文字列投げるかどっちかにしてほしい・・・。
