say i have these many file in a directory named exam.
1)/exam/newfolder/link.txt.
2)/exam/newfolder1/
and i create a tar say exam.tar
well the problem is,
when i read the tar file i dont find any metadata about the directories,as you cannot create a tar containig empty directories.

Friends,
I need help with the following in UNIX.
Merge all csv files in one folder considering only 1 header row and ignoring header of all other files.
FYI - All files are in same format and contains same headers.
Thank you (4 Replies)
Hi,
I have an input like this
1 2 3 4
2 3 4 5
4 5 6 7
I would like to count the no. of columns and print a header with a prefix "Col".
I would also like to count the no. of rows and print as first column with each line number with a prefix "Row"
So, my output would be

Hello There...
I have a sample input file ..

I will be doing some manipulations on all the records except the header, but the header should always be... (2 Replies)
Hi all,
Say i have multiple files x1 x2 x3 x4, all with common header (date, time, year, age),,
How can I merge them to one singe file "X" in shell scripting
Thanks for your suggestions. (2 Replies)
I've been struggling with this one for quite a while and cannot seem to find a solution for this find/replace scenario. Perhaps I'm getting rusty.
I have a file that contains a number of metrics (exactly 3 fields per line) from a few appliances that are collected in parallel. To identify the... (3 Replies)

SGBEQU(l) ) SGBEQU(l)
NAME
SGBEQU - compute row and column scalings intended to equilibrate an M-by-N band matrix A and reduce its condition number
SYNOPSIS
SUBROUTINE SGBEQU( M, N, KL, KU, AB, LDAB, R, C, ROWCND, COLCND, AMAX, INFO )
INTEGER INFO, KL, KU, LDAB, M, N
REAL AMAX, COLCND, ROWCND
REAL AB( LDAB, * ), C( * ), R( * )
PURPOSE
SGBEQU computes row and column scalings intended to equilibrate an M-by-N band matrix A and reduce its condition number. R returns the row
scale factors and C the column scale factors, chosen to try to make the largest element in each row and column of the matrix B with ele-
ments B(i,j)=R(i)*A(i,j)*C(j) have absolute value 1.
R(i) and C(j) are restricted to be between SMLNUM = smallest safe number and BIGNUM = largest safe number. Use of these scaling factors is
not guaranteed to reduce the condition number of A but works well in practice.
ARGUMENTS
M (input) INTEGER
The number of rows of the matrix A. M >= 0.
N (input) INTEGER
The number of columns of the matrix A. N >= 0.
KL (input) INTEGER
The number of subdiagonals within the band of A. KL >= 0.
KU (input) INTEGER
The number of superdiagonals within the band of A. KU >= 0.
AB (input) REAL array, dimension (LDAB,N)
The band matrix A, stored in rows 1 to KL+KU+1. The j-th column of A is stored in the j-th column of the array AB as follows:
AB(ku+1+i-j,j) = A(i,j) for max(1,j-ku)<=i<=min(m,j+kl).
LDAB (input) INTEGER
The leading dimension of the array AB. LDAB >= KL+KU+1.
R (output) REAL array, dimension (M)
If INFO = 0, or INFO > M, R contains the row scale factors for A.
C (output) REAL array, dimension (N)
If INFO = 0, C contains the column scale factors for A.
ROWCND (output) REAL
If INFO = 0 or INFO > M, ROWCND contains the ratio of the smallest R(i) to the largest R(i). If ROWCND >= 0.1 and AMAX is neither
too large nor too small, it is not worth scaling by R.
COLCND (output) REAL
If INFO = 0, COLCND contains the ratio of the smallest C(i) to the largest C(i). If COLCND >= 0.1, it is not worth scaling by C.
AMAX (output) REAL
Absolute value of largest matrix element. If AMAX is very close to overflow or very close to underflow, the matrix should be
scaled.
INFO (output) INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
> 0: if INFO = i, and i is
<= M: the i-th row of A is exactly zero
> M: the (i-M)-th column of A is exactly zero
