I have one f77 file,which was created on SunSparc machine.I know that each record contains 5 reals and one integer.Is there any way how I could unpack that file on my Ubuntu 16.04 Intel little-endian machine?I am giving part of the hexdump

    Perl and its handy 'unpack' function can come to your rescue here. See perlmonks.org/?node_id=718410 where there's some examples. Commented Jun 17, 2016 at 19:08

Radare is a binary exploration toolkit with nice data-carving features which should allow you to extract the data (and help you figure out the exact storage format and endianness).
