私の電話の内線番号にアクセスできない場合を知らせるBashスクリプトは何ですか？

電話内線番号にアクセスできないときに電子メールで通知するbashを作成する方法はありますか？

出力は以下から来ます。/var/log/asterisk/full

ご覧のとおり、人々が電話をかけることができないと文句を言うまで、私は電話が切れたとは思わなかった。

これまで私がしたこと：

#!/bin/bash

email="[email protected]"

offlineExtensions=$(cat /var/log/asterisk/full | grep -i unreachable)


if [ "$offlineExtensions" ]
then
printf 'Extensions that are currently offline...\n''\n'"$offlineExtensions" | mail -s 'Extensions OFFLINE' "$email"
fi

使用したいのですが、sedbashawkスクリプトは完全に初めてです。

Asterisk log file拡張機能にアクセスできないことを確認するために、このスクリプトを継続的に確認することをお勧めします。
