Hi,
I'm trying to use sed within a shell script (bash, running ubuntu). The command works fine from the command line, but when I use it within the script, rather than creating a file with the name I've specified, it creates one that ends with a question mark '?' when you use ls, e.g.... (3 Replies)

Hi All,
I have a script that does daily checks on my storage environment and is run from an AIX host.
The script currently works great but I have been changing and updating bits of it to make it easier for my lesser colleagues to understand :p
However now with the updates I have made I... (1 Reply)
I'm working on a project that requires me to compress then relocate directories to a different location based on their last date of modification. After running the script I check to see if it worked, and upon unzipping the tar.gz using I created everything that should be there is. I then performed... (4 Replies)
Hi,
I am trying to create a lock file with the following code but for some reason after file is created it has
wrong name "PASP?.lock??"
Please let us know how to get rid of these '??' from file name and from where they are coming?

I am new to Linux. Using latest version of Ubuntu.
I want to make a script that creates a 1GB file filled with zeros using dd and then formats the file as vfat with a label of "MYFILE".
If anyone can help me it would be appreciated. (9 Replies)
I have the following script
#!/bin/sh
Usage () {

exit 1
}
if

DLAGTS(l) ) DLAGTS(l)
NAME
DLAGTS - may be used to solve one of the systems of equations (T - lambda*I)*x = y or (T - lambda*I)'*x = y,
SYNOPSIS
SUBROUTINE DLAGTS( JOB, N, A, B, C, D, IN, Y, TOL, INFO )
INTEGER INFO, JOB, N
DOUBLE PRECISION TOL
INTEGER IN( * )
DOUBLE PRECISION A( * ), B( * ), C( * ), D( * ), Y( * )
PURPOSE
DLAGTS may be used to solve one of the systems of equations (T - lambda*I)*x = y or (T - lambda*I)'*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.
ARGUMENTS
JOB (input) 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 equa-
tions (T - lambda*I)x = y are to be solved and, if overflow would otherwise occur, the diagonal elements of U are to be per-
turbed. See argument TOL below. = 2: The equations (T - lambda*I)'x = y are to be solved, but diagonal elements of U are not to
be perturbed. = -2: 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.
N (input) INTEGER
The order of the matrix T.
A (input) DOUBLE PRECISION array, dimension (N)
On entry, A must contain the diagonal elements of U as returned from DLAGTF.
B (input) DOUBLE PRECISION array, dimension (N-1)
On entry, B must contain the first super-diagonal elements of U as returned from DLAGTF.
C (input) DOUBLE PRECISION array, dimension (N-1)
On entry, C must contain the sub-diagonal elements of L as returned from DLAGTF.
D (input) DOUBLE PRECISION array, dimension (N-2)
On entry, D must contain the second super-diagonal elements of U as returned from DLAGTF.
IN (input) INTEGER array, dimension (N)
On entry, IN must contain details of the matrix P as returned from DLAGTF.
Y (input/output) DOUBLE PRECISION array, dimension (N)
On entry, the right hand side vector y. On exit, Y is overwritten by the solution vector x.
TOL (input/output) 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 (output) INTEGER
= 0 : successful exit
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.
