bash スクリプトでファイルをコピーしたいのですが、時間の経過とともにファイル名が変わります。ただし、ファイル名の最初と最後は同じままです。

方法があるので、次のようにファイルを取得します:

  cp start~end.jar

どこで ~ は何でもいいですか?

これが違いを生む場合、cpコマンドはubuntuマシンでbashスクリプトを実行します。

glob（start*end）は、一致するすべてのファイルを提供します。

Expansion > Pathname Expansion > Pattern Matchingより具体的な制御については、bashマニュアルのセクションを確認してください

   *      Matches any string, including the null string.
   ?      Matches any single character.
   [...]  Matches any one of the enclosed characters.  A pair of characters separated by a hyphen denotes a range expression; any character that sorts between those two characters, inclusive, using the current locale's collat-
          ing sequence and character set, is matched.  If the first character following the [ is a !  or a ^ then any character not enclosed is matched.  The sorting order of characters in range expressions  is  determined  by
          the  current locale and the value of the LC_COLLATE shell variable, if set.  A - may be matched by including it as the first or last character in the set.  A ] may be matched by including it as the first character in
          the set.
