I'm unable to reproduce this issue. I've tried the above command on two different machines, one of which is an RPi3 similar to yours (armv7l with split version 8.23), the other an amd64 machine with split version 8.25 . For completeness, these are the commands I've used: $ dd if=/dev/urandom of=largefile bs=1M count=100 $ sha1sum largefile 087fd7665a93875e69af2b9b2fd04aed6681b944 largefile $ split -b 3276800 -d largefile largefile. $ sha1sum largefile.* > hash-amd64 [ copy 'largefile' to the RPi3 machine, snf run there: ] $ sha1sum largefile 087fd7665a93875e69af2b9b2fd04aed6681b944 largefile $ split -b 3276800 -d largefile largefile. $ sha1sum largefile.* > hash-rpi3 The resulting two hash files (hash-amd64 and hash-rpi3) are identical in my case - indicating the generated split files are identical on both machines with using "split -b". As an additional verification, concatenating the split files should result in the same sha1 checksum as the original file, on both machines (this should be true even if the split used differnt "-b X" value) $ cat largefile.* | sha1sum 087fd7665a93875e69af2b9b2fd04aed6681b944 - If you observe different result, please try the above commands and let us know which ones differ (e.g. is the checksum of the input file the same on both machines, is the checksum of the concatenated files the same on both machines). regards, - assaf
