Please try the current version coreutils 9.1, which has bug fixes in this area. Also, there's no need to cc. rms and tg; they're not working on 'split' any more. Thanks.

Where do I report a serious data loss bug with GNU's split command? Example: $ dd if=/dev/random of=file bs=262144 count=1 # Create file containing 262144 bytes $ split -n 1/2 file | wc -c 131072 $ split -n 2/2 file | wc -c 0 # SHOULD BE 131072 split -n 1/3 file | wc -c 87381 split -n 2/3 file | wc -c 87381 split -n 3/3 file | wc -c 0 # SHOULD BE 87382 The Last Chunk is completely missing, as you can see in both above examples. Additionally, if the input file is larger than 2^18 = 262144 bytes, the Last Chunk generated by "split -n K/N file" is then truncated (i.e. many bytes are missing, from the beginning of the Last Chunk). Here's the version number I'm running: $ split --version split (GNU coreutils) 8.32 Copyright (C) 2020 Free Software Foundation, Inc.
