Utiliser un outil de comparaison comme Incomparable , KDiff3 , ou Forcément devrait être suffisant.
METTRE À JOUR:
Je me sentais généreux ce matin alors je vous ai concocté cela. Devrait faire ce que tu veux.
Quelques notes:
1.) Ce code gérera les doublons. Par exemple, si une ligne avec le même texte apparaît deux fois dans le petit fichier, elle est censée apparaître deux fois dans le gros fichier.
2.) Ce code ignore la commande de ligne selon votre cas d'utilisation.
3.) Petit bug concernant les lignes vierges à la fin d'un fichier que je ne voulais pas gâcher. Ce code traite une ligne vide comme une ligne comme n'importe quelle autre ligne tant qu'elle ne se trouve pas à la fin du fichier, auquel cas une ligne vide est autorisée (et ignorée). Par exemple, si le petit fichier comporte 3 lignes vierges à la fin du fichier et aucune autre ligne vierge, alors le fichier volumineux doit comporter au moins 2 lignes vierges au milieu des autres lignes ou 3 lignes vierges au début. fin du fichier.
Courir:
1.) Assurez-vous d'avoir un JDK installée
2.) Assurez-vous que Java est sur votre chemin. Si vous utilisez un système Windows, accédez au Panneau de configuration & gt; Système & gt; Paramètres système avancés & gt; Variables d'environnement et sélectionnez Path sous la section Variables système. Ajoutez l’emplacement de votre dossier JDK bin à la variable de chemin d’accès, en veillant à bien le séparer de l’entrée précédente par un point-virgule.
C:\Program Files (x86)\Java\jdk1.6.0_38\bin;
3.) Copiez le code ci-dessous dans un fichier nommé FileLineComparator.java
4.) Ouvrez une invite de commande et accédez au répertoire contenant le fichier que vous venez de créer.
5.) Type javac FileLineComparator.java
6.) Type java -cp . FileLineComparator
7.) Profitez!
