duff

Duplicate file finder. More information: https://github.com/elmindreda/duff.

• Find duplicate files recursively:

duff -r {{path/to/directory}}

• List all but one file from each cluster of duplicates:

duff -er {{path/to/directory}}

• List unique files:

duff -ur {{path/to/directory}}

• Use SHA-256 instead of SHA-1:

duff -d sha256 {{path/to/directory}}

• Compare files byte by byte instead of using digests:

duff -t {{path/to/directory}}

• Include hidden files and directories when searching recursively:

duff -ar {{path/to/directory}}
