Wow, coreutils 9.1 indeed fixes this data loss issue with "split -n K/N", Thanks Paul! -- https://internet-in-a-box.org https://twitter.com/internet_in_box

bug#55093: "split -n K/N " BUG: Last Chunk incomplete if input file >= 262144 bytes
Hello ! 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.
