Sort and Split file with header and custom name
Hi,

I am using SUN SOLARIS (SunOS sun4v sparc SUNW, T5240).
I have a huge data file with header and trailer. This file gets used into an ETL process. ETL skips the header record (which is the first record of the file) and loads the rest of the record. The file can be delimited (comma, tab, pipe) or fixed width.

I am trying to write a script that:
  1. Sorts the records by first field. The value of first field is “Q” or “E”. So all “Q”record should sort first then “E” records.
  2. After the sort above is complete, I want to split the file on every 30,000 records with rules below:
A. The first record in every split file is a header record or blank record- starting with "H"
B. The split file needs to have same name as master file with __(double underscore) and the number.

For e.g:
Master File name is: MasterFile-HP-import-20151006.txt
Split file name needs to be : MasterFile-HP-import-20151006__1.txt ; MasterFile-HP-import-20151006__2.txt and so on.

I tried the two things below for file split:

Code:
split -dl 30000 MasterFile-HP-import-20151006.txt MasterFile-HP-import-20151006__

But getting error "split: illegal option – d error"

Also, tried the solution that I got from internet:
Code:
awk '{filename = " MasterFile-HP-import-20151006__" int((NR-1)/30000) ".txt"; print >> filename}' MasterFile-HP-import-20151006.txt

But getting an error: awk: too many output files 10 . It generates the first 10 files and gives error on 11th file.


I would appreciate any help.


Thanks
