録画サーバー用スクリプト

各ファイルに関する説明

• smb.conf

Samba向けの設定

• autoshutdown.sh

録画終了後に自動的にシャットダウンを行う.これはcronで定期的に動かす.なおこのスクリプトが起動時に誰もSSHに接続していないかつSambaを利用していない活録画していないかつ次の予約が30分以内にない場合は次の予約時間の5分前に起動するようにしてからシャットダウンする

• chinachuNext

要Python 3.Chinachuの次の予約時間を見てUnix Timeで返す

• config.json

Chinachu用の設定.

autoshutdown.sh

#!/bin/bash -x

# chinachuで録画時間を見て自動的にシャットダウンします.

WAKEUPTIME=`python3 /usr/local/bin/chinachuNext`

# SSH ログインしているユーザーがいない
if [ `who | wc -l` -eq 0 ]; then
    # 利用者がいない
    if [ `smbstatus -L | wc -l` -eq 2 ];then
	# 録画中または番組表更新中ではない
	if [ `ps aux | grep recpt1 | wc -l` -le 1 ];then
	    NOW=`date +%s`	
	    if [ `expr $WAKEUPTIME - $NOW` -gt 1800 ]; then
		echo 0 > /sys/class/rtc/rtc0/wakealarm
		echo $WAKEUPTIME > /sys/class/rtc/rtc0/wakealarm
