launchdを使ってhomebrewを自動更新(update/upgrade)

パッケージ管理システムのhomebrewを使用していますが、updateやupgradeを自身でやるのが面倒なので、launchdを使って自動化します。

環境

macOS Sierra(10.12.5)

事前準備

定期実行にはlaunchdを使用しますが、更新が完了したことを通知したいので、terminal-notifierも使用します。これもhomebrewでインストールします。

$ brew install terminal-notifier

plistファイル作成

以下内容のファイルを~/Library/LaunchAgents/localhost.homebrew-upgrade.plistという名前で作成します。

※ 起動時、または6時間毎に実行するようにしてます。

<?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>localhost.homebrew-upgrade</string>
    <key>ProcessType</key>
    <string>Background</string>
    <key>ProgramArguments</key>
    <array>
        <string>/bin/sh</string>
        <string>-c</string>
        <string>/usr/local/bin/brew update &amp;&amp; /usr/local/bin/brew upgrade &amp;&amp; /usr/local/bin/terminal-notifier -title 'homebrew' -message 'homebrew upgraded'</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>StandardErrorPath</key>
    <string>/tmp/localhost.homebrew-upgrade.stderr</string>
    <key>StandardOutPath</key>
    <string>/tmp/localhost.homebrew-upgrade.stdout</string>
    <key>StartCalendarInterval</key>
    <dict>
        <key>Hour</key>
        <integer>6</integer>
    </dict>
</dict>
</plist>

launchdに登録

以下を実行

launchctl load ~/Library/LaunchAgents/localhost.homebrew-upgrade.plist

launchdから削除

以下を実行

launchctl unload ~/Library/LaunchAgents/localhost.homebrew-upgrade.plist
