私の NAS は以下の形式でログファイルを作成します。
<30>1 2014-07-21T05:02:10+02:00 ABC-NAS qlogd 6432 - - qlogd[6432]: event log: Users: Glacier, Source IP: 127.0.0.1, Computer name: localhost, Content: [Glacier] Backup job [Backup ABC-PC] finished successfully

BASH スクリプトを使用して、次の内容のみを含むテキストファイルを作成したいと思います。
Monday 21 July 2014 - 04:10 AM
Glacier Backup job [Backup ABC-PC] finished successfully
Monday 21 July 2014 - 07:02 AM
Glacier Backup job [Backup ABC-HTPC] finished successfully
等々。
cat と grep を試してみましたが、すぐに複雑になりすぎてしまいます。正しい方向に導いてくれる人はいますか?
答え1
これは非常にシンプルなブルートフォースbashスクリプトです
cat log | cut -d " " -f 2,20- | while read -r date message; do
echo $date
echo $message
done
サンプル出力
2014-07-21T05:02:10+02:00
[Glacier] Backup job [Backup ABC-PC] finished successfully
2014-07-21T05:02:27+02:00
[Glacier] Backup job [Backup ABC-HTPC] finished successfully
より多くの機能をご希望の場合は、Python を学習することを強くお勧めします。
