$ 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。
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。
代码如下:
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。
