macで/var/log/cronを記録したい

linuxだと普通にログ取られてるのにMacは無効だったので有効化します。

#手順

/etc/syslog.conf に以下を追記

/etc/syslog.conf

cron.*      /var/log/cron.log

/System/Library/LaunchDaemons/com.vix.cron.plist 修正

1. ProgramArgumentsに-xとmiscを追加
2. StandardErrorPath を追加

/System/Library/LaunchDaemons/com.vix.cron.plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
    "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.vix.cron</string>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/sbin/cron</string>
        <string>-x</string>
        <string>misc</string>
    </array>
    <key>KeepAlive</key>
    <dict>
        <key>PathState</key>
        <dict>
            <key>/etc/crontab</key>
            <true/>
        </dict>
    </dict>
    <key>QueueDirectories</key>
    <array>
        <string>/usr/lib/cron/tabs</string>
    </array>
    <key>EnableTransactions</key>
    <true/>
    <key>StandardErrorPath</key>
    <string>/var/log/cron.log</string>
</dict>
</plist>
