czkawka是最新的重复文件查找工具，基本可以替换FSlint
FSlint is a utility to find and clean various forms of lint on a filesystem.
I.E. unwanted or problematic cruft in your files or file names.
For example, one form of lint it finds is duplicate files.
It has both GUI and command line modes.
For more info please see the FAQ.
[Update: Please see the czkawka project, a rust reimplementation,
which is more actively maintained, and easier to install on modern systems.]
ubuntu 使用应用商店snap安装：
sudo snap install czkawka
By default, Snap can only access the files in your home directory. You have to allow czkawka access to all the drives:
sudo snap connect czkawka:removable-media
