iphone自动下载当天VOA

前面一篇文章也是下载VOA，但是由于iphone cron不能在休眠时用而需要配合电脑才能下载。
后来研究了一下iphone的启动步骤，发现可以在/System/Library/LaunchDaemons添加定时job.所以整个iphone自动下载当天VOA设置如下：
1.脚本： /var/mobile/sh/getVoa.sh

cd /var/mobile/voa/
today=`date +%m-%d|sed 's/^0\+//'|sed 's/-0/-/'`
mkdir $today
cd $today
`wget -O voa.html http://www.51voa.com/`
domain="http://www.51voa.com"
urlList=`sed 's/"/\n/g' /var/mobile/voa/$today/voa.html | grep -C 4 $today |grep "\(VOA_Special_English\)\|\(VOA_Standard_English/\)\|\(Voa_English_Learning\)/.*html"`
echo $urlList
for i in $urlList
do
`wget -O temp.html ${domain}${i}`
mp3=`sed 's/"/\n/g' /var/mobile/voa/$today/temp.html | grep "/path.asp?url"`
echo "------------------$mp3"
if [ -n "$mp3" ]; then
echo $mp3
`wget $domain$mp3 --content-disposition`
fi
lrc=`sed 's/\("\|><\|href=\)/\n/g' /var/mobile/voa/$today/temp.html| grep \.lrc|awk '{print $1}'|sed 's/img//g'`
echo "------------------$lrc"
if [ -n "$lrc" ]; then
echo $lrc
`wget $domain$lrc  --content-disposition`
fi
done
rm  *html

2./System/Library/LaunchDaemons添加文件 com.downvoa.plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>Label</key>
                <string>com.downvoa</string>
                <key>ProgramArguments</key>
                <array>
                                <string>/var/mobile/sh/getvoa.sh</string>
                </array>
        <key>StartCalendarInterval</key>
        <dict>
                <key>Hour</key>
                <integer>22</integer>
                <key>Minute</key>
                <integer>55</integer>
        </dict>
        <key>UserName</key>
        <string>root</string>
</dict>
</plist>

3.加载此文件：launchctl load com.downvoa.plist 

那么每晚的22：55分iphone4就会去下载当天的voa，保存在/var/mobile/sh/{月-日} 的文件夹下。
