パッチ：パッチ入力でゴミのみが見つかりました
次のコマンドでdiff.txtファイルを作成しました（〜から実行）：
diff -r /full/path/to/directory/A /full/path/to/directory/B > diff.txt
生成されたdiffファイルは問題ありません。
実行する（常に〜から）
patch -p0 <diff.txt
または私も試しました：
patch <diff.txt
/ full/path/to/directory/Aにあるファイルに変更を適用して、操作後にそれらが/ full/path/to/directory/Bにあるファイルと同じになるようにすると思います
しかし、それは言うだけです*パッチ入力でゴミのみが見つかりました。
何が欠けていますか？
編集：これがdiffファイル全体です：

"diff -ruN path1 path2"を使用して差分を生成し、 "patch -p {N} <patchfile"を使用してパッチを適用します。Nは、差分のファイルから削除するパスのプレフィックスを決定します。パッチを見て、「diff」行を分析して、何を取り除く必要があるかを確認してください。 （参照： man patch ）。パッチを適用する前に、「patch --dry-run -p0 <patchfile」を使用して、すべてが少なくとも合理的に正常であることを確認してください。
編集：通常のdiff、unified diff（-u）およびコンテキスト差分（-c）、そしてファイル名が単に「通常の」差分に含まれていないことがわかります。 「diff」コマンドはありますが、パッチするファイル名はありません。 （実際の「diff」出力はプラットフォームごと、プログラムごとに少し異なり、patchはパッチ形式を決定するために少し補間する必要があることにも注意してください。間違ったオプションを与えた）。
