注意 ，命令行工具默认不在环境的路径中，你不能像典型的命令那样运行它。在Ubuntu中，你可以在/usr/share/fslint/fslint下找到它。因此，如果你要在一个单独的目录运行fslint完整扫描，下面是Ubuntu中的运行命令：
　　cd /usr/share/fslint/fslint
　　./fslint /path/to/directory
　　这个命令实际上并不会删除任何文件。它只会打印出重复文件的列表-你需要自己做接下来的事。
$ /usr/share/fslint/fslint/findup --help
find dUPlicate files.
Usage: findup [[[-t [-m|-d]] | [--summary]] [-r] [-f] paths(s) ...]
If no path(s) specified then the current directory is assumed.
When -m is specified any found duplicates will be merged (using hardlinks).
When -d is specified any found duplicates will be deleted (leaving just 1).
When -t is specfied， only report what -m or -d would do.
When --summary is specified change output format to include file sizes.
You can also pipe this summary format to /usr/share/fslint/fslint/fstool/dupwaste
to get a total of the wastage due to duplicates.
