+> More information: <https://github.com/pkolaczk/fclones>.
+
+- Search for duplicate files in the current directory:
+
+`fclones group .`
+
+- Search multiple directories for duplicate files and cache the results:
+
+`fclones group --cache {{path/to/directory1 path/to/directory2}}`
+
+- Search only the specified directory for duplicate files, skipping subdirectories and save the results into a file:
+
+`fclones group {{path/to/directory}} --depth 1 > {{path/to/file.txt}}`
+
+- Move the duplicate files in a TXT file to a different directory:
+
+`fclones move {{path/to/target_directory}} < {{path/to/file.txt}}`
+
+- Perform a dry run for soft links in a TXT file without actually linking:
+
+`fclones link --soft < {{path/to/file.txt}} --dry-run 2 > /dev/null`
+
+- Delete the newest duplicates from the current directory without storing them in a file:
+
+`fclones group . | fclones remove --priority newest`
+
+- Preprocess JPEG files in the current directory by using an external command to strip their EXIF data before matching for duplicates:
+
+`fclones group . --name '*.jpg' -i --transform 'exiv2 -d a $IN' --in-place`
