Combine multiple Files into one big file

Hi Ppl,

I have a requirement like i will be getting files of huge size daily and if the file size is so huge ,the files will be split into many parts and sent.The first file will have the header details followed by detail records and the consecutive files will have detail records and the last file will have the trailer details.I need to merge all these files into one single file in the order Header record then detail records then trailer record.

Example,
Filename pattern is Daily_report_1111_20111115 & Daily_report_2222_20111115.
If the file size is huge it will be split and sent as

Daily_report_1111_20111115_1
Daily_report_1111_20111115_2
Daily_report_1111_20111115_3
Daily_report_1111_20111115_4

Daily_report_2222_20111115_1
Daily_report_2222_20111115_2
Daily_report_2222_20111115_3
Daily_report_2222_20111115_4.

I need to concatenate all the Daily_report_1111_20111115_1,2,3,4 files into one big file Daily_report_1111_20111115 with contents of Daily_report_1111_20111115_1 in the top followed by the contents of the files Daily_report_1111_20111115_2,3,4.So the final output file should be Daily_report_2222_20111115 with contents of all 4 files in the order received(the order of the files will be present in the filename like _ 1,2,3,4)

Similarly for Daily_report_2222_20111115 files.

The requirement is the date 20111115(which is in the filename) will keep changing and we might get multiple days files on the same day.so i need to write and automate the script so that it looks out for the files with the same date and check the filename pattern(either Daily_report_1111_YYYYMMDD or Daily_report_2222_YYYYMMDD and concatenate them into one single file based on the filenames like _1,2,3 etc.

Please help me out!

RAGATOR(1)						      General Commands Manual							RAGATOR(1)

NAME

       ragator - aggregate argus(8) data file entries.

COPYRIGHT

       Copyright (c) 2000-2003 QoSient. All rights reserved.

SYNOPSIS

       ragator [-f ragator.conf] [raoptions]

DESCRIPTION

       Ragator	reads argus(8) data from an argus-file, and merges matching argus flow activity records together.  In its default mode of options,
       this effectively converts argus(8) files from detail to non-detail mode, and merges periodic flow report records to a single argus  record,
       thus compressing the argus(8) file to a reduced size.

       You can modify the aggregation strategy used by ragator to merge records together, by using the -f ragator.conf option.	See ragator(5) for
       a complete description of the format and syntax of the flow model file.

OPTIONS

       Ragator, like all ra based clients, supports a number of ra options including filtering of input argus records through a terminating filter
       expression.  See ra(1) for a complete description of ra options.
