Hi All,
I am trying to split a record into multiple records based on a value.
Input.txt
"A",1,0,10
"B",2,0,10,15,20
"C",3,11,14,16,19,21,23
"D",1,0,5
My desired output is:
"A",1,0,10
"B",2,0,10
"B",2,15,20
"C",3,11,14
"C",3,16,19
"C",3,21,23 (4 Replies)

dump
DUMP(5) File Formats Manual DUMP(5)NAME
dump, ddate - incremental dump format
SYNOPSIS
#include <sys/types.h>
#include <sys/ino.h>
# include <dumprestor.h>
DESCRIPTION
Tapes used by dump and restor(1) contain:
a header record
two groups of bit map records
a group of records describing directories
a group of records describing files
The format of the header record and of the first record of each description as given in the include file <dumprestor.h> is:
NTREC is the number of 512 byte records in a physical tape block. MLEN is the number of bits in a bit map word. MSIZ is the number of bit
map words.
The TS_ entries are used in the c_type field to indicate what sort of header this is. The types and their meanings are as follows:
TS_TAPE Tape volume label
TS_INODE
A file or directory follows. The c_dinode field is a copy of the disk inode and contains bits telling what sort of file this is.
TS_BITS A bit map follows. This bit map has a one bit for each inode that was dumped.
TS_ADDR A subrecord of a file description. See c_addr below.
TS_END End of tape record.
TS_CLRI A bit map follows. This bit map contains a zero bit for all inodes that were empty on the file system when dumped.
MAGIC All header records have this number in c_magic.
CHECKSUM
Header records checksum to this value.
The fields of the header structure are as follows:
c_type The type of the header.
c_date The date the dump was taken.
c_ddate The date the file system was dumped from.
c_volume The current volume number of the dump.
c_tapea The current number of this (512-byte) record.
c_inumber
The number of the inode being dumped if this is of type TS_INODE.
c_magic This contains the value MAGIC above, truncated as needed.
c_checksum
This contains whatever value is needed to make the record sum to CHECKSUM.
c_dinode This is a copy of the inode as it appears on the file system; see filsys(5).
c_count The count of characters in c_addr.
c_addr An array of characters describing the blocks of the dumped file. A character is zero if the block associated with that character
was not present on the file system, otherwise the character is non-zero. If the block was not present on the file system, no
block was dumped; the block will be restored as a hole in the file. If there is not sufficient space in this record to describe
all of the blocks in a file, TS_ADDR records will be scattered through the file, each one picking up where the last left off.
Each volume except the last ends with a tapemark (read as an end of file). The last volume ends with a TS_END record and then the tape-
mark.
The structure idates describes an entry of the file /etc/ddate where dump history is kept. The fields of the structure are:
id_name The dumped filesystem is `/dev/id_nam'.
id_incno The level number of the dump tape; see dump(1).
id_ddate The date of the incremental dump in system format see types(5).
