Extracting Logfile Entries
Hello All,
I am trying to write a KSH script that would extract lines from a logfile, within a certain timeframe, in reverse order.
Ex.
-Sample logfile-
INFO 2006-07-12 00:23:00 - ModeDecision Time in WF:27
INFO 2006-07-12 00:24:00 - NRT_MQ_RES:108
INFO 2006-07-12 00:25:00 - getRecords() :R4000 :37
INFO 2006-07-12 00:26:00 - ModeDecision Time in WF:43
INFO 2006-07-12 00:27:00 - JDBC [PADRECORD] : 5
From the sample logfile above, I am needing to extract the lines starting from '00:27:00' to three minutes prior (00:24:00). I could not find anything from the 'date' command that would reverse time.
Any help would be greatly appreciated!

dsterf.f
dsterf.f(3) LAPACK dsterf.f(3)
NAME
dsterf.f -
SYNOPSIS
Functions/Subroutines
subroutine dsterf (N, D, E, INFO)
DSTERF
Function/Subroutine Documentation
subroutine dsterf (integerN, double precision, dimension( * )D, double precision, dimension( * )E, integerINFO)
DSTERF
Purpose:
DSTERF computes all eigenvalues of a symmetric tridiagonal matrix
using the Pal-Walker-Kahan variant of the QL or QR algorithm.
Parameters:
N
N is INTEGER
The order of the matrix. N >= 0.
D
D is DOUBLE PRECISION array, dimension (N)
On entry, the n diagonal elements of the tridiagonal matrix.
On exit, if INFO = 0, the eigenvalues in ascending order.
E
E is DOUBLE PRECISION array, dimension (N-1)
On entry, the (n-1) subdiagonal elements of the tridiagonal
matrix.
On exit, E has been destroyed.
INFO
INFO is INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
> 0: the algorithm failed to find all of the eigenvalues in
a total of 30*N iterations; if INFO = i, then i
elements of E have not converged to zero.
