i want to copy a filea.dat to a file name in the format
of filea_yyyymmdd_hhmi.dat
using something like DTSTAMP=$(date "+%Y%m%d"),
which puts it in format filea_yyyymmdd.dat (5 Replies)
Hi Everyone,
I want to delete some files in a path based on the time stamp of the file that is i want to delete the file once in a month.
Can any one help me on this?
Thanks in advance (2 Replies)
Hi All,
I know the timestamp of a file. Now i would like to list all the files in the with the same time stamp in the same file.
Any help would be appreciated.
Thanks.

Hi
I have to move files between file systems but files in new file system must have the same attributes as in old one (privileges, time stamp etc).
Which tool is best :
- ufsdump / ufsrestore
- tar
- cpio
- pax
- dd
- mv
Or maybe there is sth else, you suggest to use.
Thx for help (5 Replies)
Hi,
As i know , we can change the time stamp of a file by touch command, i did change in a file and it is looking as given
# ls -l abcd
-rw-r--r-- 1 batsoqa sicusers 0 Feb 17 2010 abcd
actually i want to see the output like this
-rw-r--r-- 1 batsoqa sicusers ... (3 Replies)
Hi All,
PFB is a requirement. I am new to shell scripting. So plz help. It would be highly appreciated.
1. choose all the log files based on a particular date (files location is '/test/domain')--i.e,we should choose all the files that are modified on 29th November, neither 28th nor 30th

Hi,
I'm trying to improve my Unix skills and I'm wondering what is the best way to move some files based on filetype and attributes like time created?
For instance, lets suppose I have a directory with many different files in it and I'd like to move all the jpgs that were created between May... (6 Replies)
Hi all,
I'm after some help with this small issue which i'm struggling to work out a fix for.
I have a file that contains records that all have a time stamp for each individual record, i need to search the file for a specific time stamp and then search back 10 seconds to see if the number... (2 Replies)
Hi All,
I am facing small problem.
i want to print file time stamp on which date file has placed in the server.
i have given some code but its not giving the year.
any help appreciated.

Below is the output now i need to filter based on latest modified timestamp.
I know 3 is the latest modified time stamp but i tried different options but only filtering docs and not on headnote..Can any one tell me how to do that..

dlagts.f(3) LAPACK dlagts.f(3)NAME
dlagts.f -
SYNOPSIS
Functions/Subroutines
subroutine dlagts (JOB, N, A, B, C, D, IN, Y, TOL, INFO)
DLAGTS
Function/Subroutine Documentation
subroutine dlagts (integerJOB, integerN, double precision, dimension( * )A, double precision, dimension( * )B, double precision, dimension( *
)C, double precision, dimension( * )D, integer, dimension( * )IN, double precision, dimension( * )Y, double precisionTOL, integerINFO)
DLAGTS
Purpose:
DLAGTS may be used to solve one of the systems of equations
(T - lambda*I)*x = y or (T - lambda*I)**T*x = y,
where T is an n by n tridiagonal matrix, for x, following the
factorization of (T - lambda*I) as
(T - lambda*I) = P*L*U ,
by routine DLAGTF. The choice of equation to be solved is
controlled by the argument JOB, and in each case there is an option
to perturb zero or very small diagonal elements of U, this option
being intended for use in applications such as inverse iteration.
Parameters:
JOB
JOB is INTEGER
Specifies the job to be performed by DLAGTS as follows:
= 1: The equations (T - lambda*I)x = y are to be solved,
but diagonal elements of U are not to be perturbed.
= -1: The equations (T - lambda*I)x = y are to be solved
and, if overflow would otherwise occur, the diagonal
elements of U are to be perturbed. See argument TOL
below.
= 2: The equations (T - lambda*I)**Tx = y are to be solved,
but diagonal elements of U are not to be perturbed.
= -2: The equations (T - lambda*I)**Tx = y are to be solved
and, if overflow would otherwise occur, the diagonal
elements of U are to be perturbed. See argument TOL
below.
N
N is INTEGER
The order of the matrix T.
A
A is DOUBLE PRECISION array, dimension (N)
On entry, A must contain the diagonal elements of U as
returned from DLAGTF.
B
B is DOUBLE PRECISION array, dimension (N-1)
On entry, B must contain the first super-diagonal elements of
U as returned from DLAGTF.
C
C is DOUBLE PRECISION array, dimension (N-1)
On entry, C must contain the sub-diagonal elements of L as
returned from DLAGTF.
D
D is DOUBLE PRECISION array, dimension (N-2)
On entry, D must contain the second super-diagonal elements
of U as returned from DLAGTF.
IN
IN is INTEGER array, dimension (N)
On entry, IN must contain details of the matrix P as returned
from DLAGTF.
Y
Y is DOUBLE PRECISION array, dimension (N)
On entry, the right hand side vector y.
On exit, Y is overwritten by the solution vector x.
TOL
TOL is DOUBLE PRECISION
On entry, with JOB .lt. 0, TOL should be the minimum
perturbation to be made to very small diagonal elements of U.
TOL should normally be chosen as about eps*norm(U), where eps
is the relative machine precision, but if TOL is supplied as
non-positive, then it is reset to eps*max( abs( u(i,j) ) ).
If JOB .gt. 0 then TOL is not referenced.
On exit, TOL is changed as described above, only if TOL is
non-positive on entry. Otherwise TOL is unchanged.
INFO
INFO is INTEGER
= 0 : successful exit
.lt. 0: if INFO = -i, the i-th argument had an illegal value
.gt. 0: overflow would occur when computing the INFO(th)
element of the solution vector x. This can only occur
when JOB is supplied as positive and either means
that a diagonal element of U is very small, or that
the elements of the right-hand side vector y are very
large.
