复制代码代码如下:$ mkdir /home/"$USER"/Desktop/tecmint && cd /home/"$USER"/Desktop/tecmint && for i in {1..15}; do echo "I Love Tecmint. Tecmint is a very nice community of Linux Users." > tecmint${i}.txt ; done 在执行以上命令后，让我们使用ls命令验证重复文件是否创建。
复制代码代码如下:$ ls -l total 60 -rw-r--r-- 1 tecmint tecmint 65 Aug 8 11:22 tecmint10.txt -rw-r--r-- 1 tecmint tecmint 65 Aug 8 11:22 tecmint11.txt -rw-r--r-- 1 tecmint tecmint 65 Aug 8 11:22 tecmint12.txt -rw-r--r-- 1 tecmint tecmint 65 Aug 8 11:22 tecmint13.txt -rw-r--r-- 1 tecmint tecmint 65 Aug 8 11:22 tecmint14.txt -rw-r--r-- 1 tecmint tecmint 65 Aug 8 11:22 tecmint15.txt -rw-r--r-- 1 tecmint tecmint 65 Aug 8 11:22 tecmint1.txt -rw-r--r-- 1 tecmint tecmint 65 Aug 8 11:22 tecmint2.txt -rw-r--r-- 1 tecmint tecmint 65 Aug 8 11:22 tecmint3.txt -rw-r--r-- 1 tecmint tecmint 65 Aug 8 11:22 tecmint4.txt -rw-r--r-- 1 tecmint tecmint 65 Aug 8 11:22 tecmint5.txt -rw-r--r-- 1 tecmint tecmint 65 Aug 8 11:22 tecmint6.txt -rw-r--r-- 1 tecmint tecmint 65 Aug 8 11:22 tecmint7.txt -rw-r--r-- 1 tecmint tecmint 65 Aug 8 11:22 tecmint8.txt -rw-r--r-- 1 tecmint tecmint 65 Aug 8 11:22 tecmint9.txt 上面的脚本创建了15个文件，名称分别为tecmint1.txt，tecmint2.txt……tecmint15.txt，并且每个文件的数据相同，如 "I Love Tecmint. Tecmint is a very nice community of Linux Users." 2、 现在在tecmint文件夹内搜索重复的文件。 $ fdupes /home/$USER/Desktop/tecmint /home/tecmint/Desktop/tecmint/tecmint13.txt /home/tecmint/Desktop/tecmint/tecmint8.txt /home/tecmint/Desktop/tecmint/tecmint11.txt /home/tecmint/Desktop/tecmint/tecmint3.txt /home/tecmint/Desktop/tecmint/tecmint4.txt /home/tecmint/Desktop/tecmint/tecmint6.txt /home/tecmint/Desktop/tecmint/tecmint7.txt /home/tecmint/Desktop/tecmint/tecmint9.txt /home/tecmint/Desktop/tecmint/tecmint10.txt /home/tecmint/Desktop/tecmint/tecmint2.txt /home/tecmint/Desktop/tecmint/tecmint5.txt /home/tecmint/Desktop/tecmint/tecmint14.txt /home/tecmint/Desktop/tecmint/tecmint1.txt /home/tecmint/Desktop/tecmint/tecmint15.txt /home/tecmint/Desktop/tecmint/tecmint12.txt 3、 使用-r选项在每个目录包括其子目录中递归搜索重复文件。 它会递归搜索所有文件和文件夹，花一点时间来扫描重复文件，时间的长短取决于文件和文件夹的数量。在此其间，终端中会显示全部过程，像下面这样。
复制代码代码如下:$ fdupes --version fdupes 1.51 11、 如果你需要关于fdupes的帮助，可以使用-h开关。 $ fdupes -h Usage: fdupes [options] DIRECTORY... -r --recurse for every directory given follow subdirectories encountered within -R --recurse: for each directory given after this option follow subdirectories encountered within （note the ":" at the end of the option, manpage for more details） -s --symlinks follow symlinks -H --hardlinks normally, when two or more files point to the same disk area they are treated as non-duplicates; this option will change this behavior -n --noempty exclude zero-length files from consideration -A --nohidden exclude hidden files from consideration -f --omitfirst omit the first file in each set of matches -1 --sameline list each set of matches on a single line -S --size show size of duplicate files -m --summarize summarize dupe information -q --quiet hide progress indicator -d --delete prompt user for files to preserve and delete all others; important: under particular circumstances, data may be lost when using this option together with -s or --symlinks, or when specifying a particular directory more than once; refer to the fdupes documentation for additional information -N --noprompt together with --delete, preserve the first file in each set of duplicates and delete the rest without prompting the user -v --version display fdupes version -h --help display this help message 到此为止了。让我知道你以前怎么在Linux中查找并删除重复文件的吧？同时，也让我知道你关于这个工具的看法。在下面的评论部分中提供你有价值的反馈吧，别忘了为我们点赞并分享，帮助我们扩散哦。
