Good luck.
I think this would probably work except I really need to know which ones
are out of sequence as is, changing the filename would eliminate that
capability and the missing files are the ones I need. See, I'm
receiving the files from a separate server and they are sent to me in
this format. I need to know which ones I /don't/ receive so I know
which ones I need to have resent. Make sense?

Yes. But you must have a pattern with which we can compare your received
files. Which is the exact pattern? If you have this clear, we can
probably solve the problem with bash.

Waiting...

Okay, here goes, the XXXX part denotes a 4 character symbol for a NWS
radar site, the 8 digits after that is the date followed by '_HHMMSS_'
of time the data was collected. The next part I'm not certain, but
believe it's the scan number of that particular radar scan, then the
last 2 digits are the part number of a complete scan. In other words, I
have a series of weather radar scans that get broken up into 'radials'
(the .bz2 files) and numbered. Our customers get fed this data through
our servers, but a couple have reported missing files. I'm trying to
track down the problem, but can't go through 2GB of volume scans every
day for possibly one missing file.

The files are stored in directories in this format: XXXX/date/ so I have
multiple volume scans in each day's directory.

Does this help?

Barely. Mark, I do agree with the rsync solution mentioned early. But, forcing it with bash, what I would do is:

1. Obtain the daily radar sites list

[rodolfoap] /home/rodolfoap > ls -1 *.bz2|sed -e "s/\(....\)\(.*.\)/\1/"|sort|uniq > radarsites.$(/bin/date "+%Y%m%d")

...the four points are the four first characters...
...you can have a predetermined file, so you can know if you have a server missing:

[rodolfoap] /home/rodolfoap > cat radarsites.$(/bin/date "+%Y%m%d")
XXXX
XYXX
XYYX
XYYY
YYYY
[rodolfoap] /home/rodolfoap > cat radarsites.official
XXXX
XYXX
XYYX
XYYY
YYYY
ZZZZ

[rodolfoap] /home/rodolfoap > diff radarsites.official radarsites.$(/bin/date "+%Y%m%d")
6d5
< ZZZZ

...That means: in the left file (official radar list) stays a value not found on the right file. You can play with the result.

2. Find the minimum and maximum values of each set. That is what you dont say. Is there an obligated minimum? maximum? Anyway, this is a list of your set ranges:

[rodolfoap] /home/rodolfoap > for a in $(cat radarsites.$(/bin/date "+%Y%m%d")); do MIN=$(ls -1 ${a}*|sort -n|head -1); MAX=$(ls -1 ${a}*|sort -n|tail -1);echo $MIN -- $MAX; done
XXXX20070515_112011_942_10.bz2 -- XXXX20070515_112011_942_40.bz2
XYXX20070515_112011_942_10.bz2 -- XYXX20070515_112011_942_40.bz2
XYYX20070515_112011_942_10.bz2 -- XYYX20070515_112011_942_40.bz2
XYYY20070515_112011_942_10.bz2 -- XYYY20070515_112011_942_40.bz2
YYYY20070515_112011_942_10.bz2 -- YYYY20070515_112011_942_40.bz2

Now you have all elements to find your missing files. If there is
anymore we can help with, please be clear.

Good luck!
