Brilliant. But I did notice that you need to compensate for hours west of GMT,
offset must be an integer number of hours, and the expression may only have one operator (ie. "EST+5+$OFFSET" is invalid)
I Have a long file like this
123122312 05/06/12
123123456 05/06/14
I want to take the difference of dates in two lines & print difference sidewise for the whole long files.
Pl help me out. (1 Reply)
I have the script which appends month and year to the name of the
file. Now every time when I append the month-year combination I
have to subtract 2 months from the current date and then append
it, since we are sending our vendor 2 months prior worth of data
eveytime.

Hi,
I have one .csv file. I have 2 date columns present in file, column 2 and column 3.
I need to calculate how many days exist between 2 dates.
I am trying to subtract date column 2 from date column 3.
Eg: my file look likes
s.no, Start_date,End_Date

Hi,
Can you please let me know code for the below (in korn shell)

c) Subtract month(s) from given timestamp
d) Subtract day(s) from give timestamp (1 Reply)
Hi,
I am running on Solaris 11.3.
I have a timestamp in this format date +%Y%m%d%H%M .
I found some forums saying to use date --d however that didn't work.
Is there a way how I can subtract days from timestamp in that format?
Thanks (12 Replies)
Hi all,
I have been researching to obtain SSL certification expiry for most of our webistes. For some cases, some hosts where not directly accessible so i finally got a solution working with curl using my proxy. This lists the expiry date which i'm finally looking for.

Hi,
In a folder, there are files. I have a script which reads the current date and subtract the modification date of each file.
How do I achieve this?
Regards,

SLAQP2(l) ) SLAQP2(l)
NAME
SLAQP2 - compute a QR factorization with column pivoting of the block A(OFFSET+1:M,1:N)
SYNOPSIS
SUBROUTINE SLAQP2( M, N, OFFSET, A, LDA, JPVT, TAU, VN1, VN2, WORK )
INTEGER LDA, M, N, OFFSET
INTEGER JPVT( * )
REAL A( LDA, * ), TAU( * ), VN1( * ), VN2( * ), WORK( * )
PURPOSE
SLAQP2 computes a QR factorization with column pivoting of the block A(OFFSET+1:M,1:N). The block A(1:OFFSET,1:N) is accordingly pivoted,
but not factorized.
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.
OFFSET (input) INTEGER
The number of rows of the matrix A that must be pivoted but no factorized. OFFSET >= 0.
A (input/output) REAL array, dimension (LDA,N)
On entry, the M-by-N matrix A. On exit, the upper triangle of block A(OFFSET+1:M,1:N) is the triangular factor obtained; the ele-
ments in block A(OFFSET+1:M,1:N) below the diagonal, together with the array TAU, represent the orthogonal matrix Q as a product of
elementary reflectors. Block A(1:OFFSET,1:N) has been accordingly pivoted, but no factorized.
LDA (input) INTEGER
The leading dimension of the array A. LDA >= max(1,M).
JPVT (input/output) INTEGER array, dimension (N)
On entry, if JPVT(i) .ne. 0, the i-th column of A is permuted to the front of A*P (a leading column); if JPVT(i) = 0, the i-th col-
umn of A is a free column. On exit, if JPVT(i) = k, then the i-th column of A*P was the k-th column of A.
TAU (output) REAL array, dimension (min(M,N))
The scalar factors of the elementary reflectors.
VN1 (input/output) REAL array, dimension (N)
The vector with the partial column norms.
VN2 (input/output) REAL array, dimension (N)
The vector with the exact column norms.
WORK (workspace) REAL array, dimension (N)
