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.

Hi,
I'm, new to shell scripting, I have a requirement where I have to split an incoming file into separate files each containing a maximum of 3 million rows.
For e.g: if my incoming file say In.txt has 8 mn rows then I need to create 3 files, in which two will 3 mn rows and one will contain 2... (2 Replies)
Hi all, I need help to split a tab-delimited list into separate files by the filename-field. The list is already sorted ascendingly by filename, an example list would look like this;

Hello,
Please help me. I have hundreds of text files composed of several rows of information and I need to separate each row into a new text file. I was trying to figure out how to split the text file into different text files, based on each row of text in the original text file. Here is an... (2 Replies)
hi
i have a requirement to input a string to a shell script and to split the string to multiple fields,
the string is copied from a row of three columns (name,age,address) in an excel sheet.
the three columns (from excel) are seperated with a tab when pasted in the command prompt, but when the ... (2 Replies)

Howdy folks, I've got a very large plain text file that I need to split into many smaller files. My script-fu is not powerful enough for this, so any assistance is much appreciated.
The file is a database dump from Cyrus IMAP server. It's basically a bunch of emails (thousands) all... (13 Replies)
Hi,
I am wanting to create a script that will construct a SQL statement based on a a space delimited string that it read from a config file.
Example of the SQL will be
For example, it will read a string like "AAA BBB CCC" and assign to a variable named IN_STRING.
I then concatenate... (2 Replies)

CTGEX2(l) ) CTGEX2(l)
NAME
CTGEX2 - swap adjacent diagonal 1 by 1 blocks (A11,B11) and (A22,B22)
SYNOPSIS
SUBROUTINE CTGEX2( WANTQ, WANTZ, N, A, LDA, B, LDB, Q, LDQ, Z, LDZ, J1, INFO )
LOGICAL WANTQ, WANTZ
INTEGER INFO, J1, LDA, LDB, LDQ, LDZ, N
COMPLEX A( LDA, * ), B( LDB, * ), Q( LDQ, * ), Z( LDZ, * )
PURPOSE
CTGEX2 swaps adjacent diagonal 1 by 1 blocks (A11,B11) and (A22,B22) in an upper triangular matrix pair (A, B) by an unitary equivalence
transformation.
(A, B) must be in generalized Schur canonical form, that is, A and B are both upper triangular.
Optionally, the matrices Q and Z of generalized Schur vectors are updated.
Q(in) * A(in) * Z(in)' = Q(out) * A(out) * Z(out)'
Q(in) * B(in) * Z(in)' = Q(out) * B(out) * Z(out)'
ARGUMENTS
WANTQ (input) LOGICAL
WANTZ (input) LOGICAL
N (input) INTEGER
The order of the matrices A and B. N >= 0.
A (input/output) COMPLEX arrays, dimensions (LDA,N)
On entry, the matrix A in the pair (A, B). On exit, the updated matrix A.
LDA (input) INTEGER
The leading dimension of the array A. LDA >= max(1,N).
B (input/output) COMPLEX arrays, dimensions (LDB,N)
On entry, the matrix B in the pair (A, B). On exit, the updated matrix B.
LDB (input) INTEGER
The leading dimension of the array B. LDB >= max(1,N).
Q (input/output) COMPLEX array, dimension (LDZ,N)
If WANTQ = .TRUE, on entry, the unitary matrix Q. On exit, the updated matrix Q. Not referenced if WANTQ = .FALSE..
LDQ (input) INTEGER
The leading dimension of the array Q. LDQ >= 1; If WANTQ = .TRUE., LDQ >= N.
Z (input/output) COMPLEX array, dimension (LDZ,N)
If WANTZ = .TRUE, on entry, the unitary matrix Z. On exit, the updated matrix Z. Not referenced if WANTZ = .FALSE..
LDZ (input) INTEGER
The leading dimension of the array Z. LDZ >= 1; If WANTZ = .TRUE., LDZ >= N.
J1 (input) INTEGER
The index to the first block (A11, B11).
INFO (output) INTEGER
=0: Successful exit.
=1: The transformed matrix pair (A, B) would be too far from generalized Schur form; the problem is ill- conditioned. (A, B) may
have been partially reordered, and ILST points to the first row of the current position of the block being moved.

In the current code both weak and strong stability tests are performed. The user can omit the strong stability test by changing the inter-
nal logical parameter WANDS to .FALSE.. See ref. [2] for details.
