Display existing hard links in result sets This is a breaking change in the plain text output, but somehow the list displayed in case of existing hard links was arbitrary, since the all the hardlinked filenames were not displayed. Here's a sample JSON result with this patch: { "file_size": 9216, "paths": [ "test_tree/f09-1_5.raw", "test_tree/f09-4_5.raw" ], "links": { "test_tree/f09-1_5.raw": [ "test_tree/f09-2_5.raw", "test_tree/f09-3_5.raw" ], "test_tree/f09-4_5.raw": [ "test_tree/f09-5_5.raw" ] } } Here the 5 files have the same contents, but there are two hardlink groups: "test_tree/f09-1_5.raw" "test_tree/f09-2_5.raw" "test_tree/f09-3_5.raw" are hard-linked, and "test_tree/f09-4_5.raw" "test_tree/f09-5_5.raw" are hard-linked. Here's the same set displayed With the regular text output: Group #5 (2 files * 9216 bytes): test_tree/f09-1_5.raw test_tree/f09-2_5.raw test_tree/f09-3_5.raw test_tree/f09-4_5.raw test_tree/f09-5_5.raw (The link file names are indented using 1 space character.)
