Hello
malaika,
I would like to bring up a few things to consider:-
- How do you know that the file is complete before you try to split it? Perhaps it gets transferred as filename.partial then renamed to filename when complete or there is a flag file such as filename.OKAY created in the next step
- Why break up the file to send it and reassemble? Have you considered rsync? If there is an interruption it can restart to catch up. You might be able to set it up to transfer then remove the original. Trial this with small files though
Does this help/hinder/miss the point?
Kind regards,
Robin

fragiso
FRAGISO(8) System Manager's Manual FRAGISO(8)
NAME
fragiso - split rpm packages from an iso and reassemble the iso later on
SYNOPSIS
fragiso make iso fiso
fragiso list fiso
fragiso fill [-m] fiso iso
DESCRIPTION
fragiso can be used to convert an iso file into a fragment file, which is a list describing all of the rpms on the iso and a data chunk
containing everything but the rpms. It is used by drpmsync when an iso needs to be transferred. The idea is that often the rpms on the iso
are already available on the destination host, so it saves bandwidth to first transfer the fragmented iso, copy the locally available rpms,
transfer the unavailable rpms and reassemble the iso file.
fragiso make converts the iso into the fragment iso, fragiso list can be used to extract the rpm information. This information consists of
the offset and length of all rpms and the lead/signature header md5sum plus the header/payload md5sum. To reassemble the iso one has to
copy the rpms at the right offset into a new file and then use fragiso fill later on to provide all data not contained in the rpms. The -m
option tells fragiso to print the resulting md5sum of the iso to stdout. It can be used for verification purposes.
