[term, Linux, high tech solution]
You can split a "binary" file into pieces with dd.
You can reassemble it with cat.
To split into 300 KB chunks:
dd if=giant_binary.tgz of=part1 bs=1024 count=300
dd if=giant_binary.tgz of=part2 bs=1024 count=300 skip=300
dd if=giant_binary.tgz of=part3 bs=1024 count=300 skip=600
dd if=giant_binary.tgz of=part4 bs=1024 count=300 skip=900
The last chunk will be exactly the right size!
All but the last chunk can be written to /dev/fd0 instead
of temporary files (count=1440 for 3.5 HD). Tar or cpio the last one.

Yes but in North America why not use ftpmail@sunsite.unc.edu
which is much faster? Send mail containing only the word "help"
to that address. Save the reply; it's slightly different than
decwrl's.
