I have a log file with date format like
10-Oct-02 13:20:29 .....
at the beginning of each line in the log file, and I need to grep data from this file to list the lines with date no longer than one days.
I tried to use awk to do this but it looks very complicated to do it.

Hi Gurus
I am getting the timestamp of the last generated log file
its like this "Oct 31 10:26"
I want to compare this timestamp with the current date in shell script. I want to compare if the
(timestamp-currentime) > 10 minutes
how do i do this.
Thanks

Hi all,
I've written a script which gives the below information...
End Date&Time: 2008-10-21 10.54.37
Now i want to calculate this time with the current time.. and if its more than 48 hours past with the current time it should echo "48 Hours back"
Please help me..

Hi to all.
When you have to compare a lot of dates in a SH code, there is a way to directly compare? For example, how can I check if two dates differ in less than a week?
Thank's for reading. (2 Replies)
Hi,
I want to convert two datetime fields to find out if the difference is one hour, in linux I've done this by converting both the datetime values to unix epoch time and subtracting them to find out if the difference is more than 3600s, however this does not work in hp-ux.
I've these... (3 Replies)
Hi All,
I am entering StartDate and EndDate as parameters to script. Want to have an check saying, "If StartDate is greater than EndDate then don't execute the script".

sdisna
sdisna.f(3) LAPACK sdisna.f(3)NAME
sdisna.f -
SYNOPSIS
Functions/Subroutines
subroutine sdisna (JOB, M, N, D, SEP, INFO)
SDISNA
Function/Subroutine Documentation
subroutine sdisna (characterJOB, integerM, integerN, real, dimension( * )D, real, dimension( * )SEP, integerINFO)
SDISNA
Purpose:
SDISNA computes the reciprocal condition numbers for the eigenvectors
of a real symmetric or complex Hermitian matrix or for the left or
right singular vectors of a general m-by-n matrix. The reciprocal
condition number is the 'gap' between the corresponding eigenvalue or
singular value and the nearest other one.
The bound on the error, measured by angle in radians, in the I-th
computed vector is given by
SLAMCH( 'E' ) * ( ANORM / SEP( I ) )
where ANORM = 2-norm(A) = max( abs( D(j) ) ). SEP(I) is not allowed
to be smaller than SLAMCH( 'E' )*ANORM in order to limit the size of
the error bound.
SDISNA may also be used to compute error bounds for eigenvectors of
the generalized symmetric definite eigenproblem.
Parameters:
JOB
JOB is CHARACTER*1
Specifies for which problem the reciprocal condition numbers
should be computed:
= 'E': the eigenvectors of a symmetric/Hermitian matrix;
= 'L': the left singular vectors of a general matrix;
= 'R': the right singular vectors of a general matrix.
M
M is INTEGER
The number of rows of the matrix. M >= 0.
N
N is INTEGER
If JOB = 'L' or 'R', the number of columns of the matrix,
in which case N >= 0. Ignored if JOB = 'E'.
D
D is REAL array, dimension (M) if JOB = 'E'
dimension (min(M,N)) if JOB = 'L' or 'R'
The eigenvalues (if JOB = 'E') or singular values (if JOB =
'L' or 'R') of the matrix, in either increasing or decreasing
order. If singular values, they must be non-negative.
SEP
SEP is REAL array, dimension (M) if JOB = 'E'
dimension (min(M,N)) if JOB = 'L' or 'R'
The reciprocal condition numbers of the vectors.
INFO
INFO is INTEGER
= 0: successful exit.
< 0: if INFO = -i, the i-th argument had an illegal value.
