Find duplicate files in some directory tree:
dupfinder path/to/dir
Some basic filtering options are available. See dupfinder -h for options.
For maximum control, you can use the find command to filter files to include,
and pass the list of files to stdin of dupfinder -0, for example:
find . -type f -print0 | dupfinder -0
To find duplicate files in multiple directory trees,
only considering filenames with extension .avi,
descending to at most 2 sub-directory levels:
find path/to/dir path/to/other/dir -name '*.avi' -maxdepth 2 | dupfinder -0
Run the ./coverage.sh helper script.
