Could one of you shad some light on this:
I need to split the file by determining the record count and than splitting it up into 4 files. Please note, this is not a fixed record length but rather a "|" delimited file.
I am not sure as how to handle reminder/offset for the 4th file.

Hello Guys,
I am new to Unix and i got one requirement where I need to split my file into maximum 5 files on below conditions, if they are splitted into less than 5 then also we are fine.
Columns D value should appear in a single file only and shouldn't continue in other files.

slarra
slarra.f(3) LAPACK slarra.f(3)NAME
slarra.f -
SYNOPSIS
Functions/Subroutines
subroutine slarra (N, D, E, E2, SPLTOL, TNRM, NSPLIT, ISPLIT, INFO)
SLARRA computes the splitting points with the specified threshold.
Function/Subroutine Documentation
subroutine slarra (integerN, real, dimension( * )D, real, dimension( * )E, real, dimension( * )E2, realSPLTOL, realTNRM, integerNSPLIT,
integer, dimension( * )ISPLIT, integerINFO)
SLARRA computes the splitting points with the specified threshold.
Purpose:
Compute the splitting points with threshold SPLTOL.
SLARRA sets any "small" off-diagonal elements to zero.
Parameters:
N
N is INTEGER
The order of the matrix. N > 0.
D
D is REAL array, dimension (N)
On entry, the N diagonal elements of the tridiagonal
matrix T.
E
E is REAL array, dimension (N)
On entry, the first (N-1) entries contain the subdiagonal
elements of the tridiagonal matrix T; E(N) need not be set.
On exit, the entries E( ISPLIT( I ) ), 1 <= I <= NSPLIT,
are set to zero, the other entries of E are untouched.
E2
E2 is REAL array, dimension (N)
On entry, the first (N-1) entries contain the SQUARES of the
subdiagonal elements of the tridiagonal matrix T;
E2(N) need not be set.
On exit, the entries E2( ISPLIT( I ) ),
1 <= I <= NSPLIT, have been set to zero
SPLTOL
SPLTOL is REAL
The threshold for splitting. Two criteria can be used:
SPLTOL<0 : criterion based on absolute off-diagonal value
SPLTOL>0 : criterion that preserves relative accuracy
TNRM
TNRM is REAL
The norm of the matrix.
NSPLIT
NSPLIT is INTEGER
The number of blocks T splits into. 1 <= NSPLIT <= N.
ISPLIT
ISPLIT is INTEGER array, dimension (N)
The splitting points, at which T breaks up into blocks.
The first block consists of rows/columns 1 to ISPLIT(1),
the second of rows/columns ISPLIT(1)+1 through ISPLIT(2),
etc., and the NSPLIT-th consists of rows/columns
ISPLIT(NSPLIT-1)+1 through ISPLIT(NSPLIT)=N.
INFO
INFO is INTEGER
= 0: successful exit
