ランダムテストログジェネレータ[閉じる]

ランダムテストログデータを生成するスクリプトを作成する必要があります。

ログデータは「|」（パイプ）で区切る必要があり、合計10,000行、各行は500バイト、各行には次の形式のランダムデータが含まれています。

date|time|pid|status|data|comment

各列の範囲：

date    : 20130101
time    : 09:00:00-11:59:59
pid     : 3000-5000
status  : OK || TEMP || PERM
data    : refer words/sentences used in whichever of the following pages and set them randomly - https://en.wikipedia.org/wiki/Amazon_S3
comment : fill in with "X" to fit one line as 500 bytes.

（例）ランダムテストログデータは次のとおりです。

これは、データに対する追加の変更を実装するために簡単に拡張できる単純なシェルスクリプトです。

  count=$((count + 1))
done

このcount変数を使用すると、10,000回繰り返すことができます。このhash変数は一種のマスクです。最後の文字列を500文字で埋めるために使用されます（値は500個のハッシュマークです）。アイデア:) printf %500s | tr " " "#"。

caseループ内の2つの文は、サンプルデータから疑似ランダム文字列を選択します。dataここでそのセクションを展開して、より多くのオプションを見ることができます。

変数割り当ては、最初の5つのフィールド（静的日付文字列、9時から11時59分59秒の間の擬似ランダムタイムスタンプ、擬似ランダムpid、選択状態コード、および選択データ文字列）を結合するためpartに使用されます。printf

次に、printfに関連付けられた文字列を印刷するように要求します。

  • 区切り記号|と
  • hashその上の痕跡

...その後、印刷文字列全体を500文字に切ります。.500 型幅指定子。
