May be it's better to use awk:
echo $sum | awk '{ printf("%c", $1) }' \
| dd of="$2" bs=1 count=1 seek=$size conv=notrunc 2>/dev/null
This version accepts decimal $sum, does not need conversion to octal.
Ane may be it's better to write whole checksum in awk, it's faster and
cleaner. See attached patch (I am sorry, I don't know how to use git-
email).
My awk magic is pretty bad, but I think this version is missing the
padding, right?
