Re: File archiving questions

[KoReE <koree@ameth.org>]

You could write a shell script using "du" to get the list of files you
want to copy.  Psuedocode would be something like:

du -k

Parse each file entry and stick it into an array of file names.
Also grab its size and stick that into a size var.

If an entry pushes the total size over 650MBs, drop the last file from
the array, and from the  size calculation, and go on to the copy
operation.

When it reaches 650MBs (650000KB)(or as close as possible based on the
above logic), stop, and do a copy to a specified dir, based on the entries
collected from "du -k".

perl may be better for this than a shell script.

between the sounds and open wide to suck it in,
I feel it move across my skin.
I'm reaching up and reaching out,
I'm reaching for the random or what ever will bewilder me.
And following our will and wind we may just go where no one's been.
We'll ride the spiral to the end and may just go where no one's been."
