I am using an array (clmlist01). I have 61 of these and have 4 or more references to each one in a block of code that I do not want to have to hardcode. With that being said, I am creating a varible and going through a for loop to create the actually name of each array. The arrays would end up... (3 Replies)
Hello,
i have another sed question.. I'm trying to do variable substition with sed and i'm running into a problem.
my var1 is a string constructed like this:
filename1 filerev1 filepath1
my var2 is another string constructed like this:
filename2 filerev2 filepath2

Hello,
Please tell me if there is a better way to get the number of elements from an array that is passed to a function.
This is what works on Solaris 8 (ksh) but it looks odd:
loop_array() {
array_name=$2
b1='\${\#'
b2='}'

I've created a series of arrays named as follows:
row1
row2
row3
.
.
.
row10
Each has 4 elements.
I'm trying to echo the array elements out in a for loop. Here's what I have:
for ((i=1;i<=10;i++))
do
for ((j=1;j<=4;j++))
do
eval out=${row`echo $i`}
echo -n $out (3 Replies)
Hi ,
I have a variable as follows,
Temp=`cat ABC.txt | cut -c5-`
This will yeild a part of the date. say , 200912.
I would like to substitute this variable's value in a filename.
eg: File200912F.zip
when i say File$TempF.zip , it is not substituting.
Any help ?
Thanks in... (2 Replies)
Hi.
I´ve a script that should substitude the 8th line in a file called xxx.num6.
The "xxx" is set by an array filled with this command:
j=0
for Par in *.sys ; do
Par=`echo $Par | sed 's/\(.*\).sys/\1/'` ;
Par2="$Par" ; echo "${Par2}"
j=$((j + 1));
done
Now i try... (0 Replies)
For example I have variable like below
echo $OUTPUT
/some/path/`uname -n`
when I try to use the variable OUTPUT like below
cd $OUTPUT or cd ${OUTPUT}
I am getting bad substituion error message
$ cd $OUTPUT
ksh: cd: bad substitution
$ cd ${OUTPUT}

Is there a way to print multiple array elements without iterating through the array using bash?
Can you do something like...
echo ${array}and get all those separate elements from the array? (2 Replies)
Hello all,
I have following piece of code which is working fine if executed standalone -
date=$1
set -A max_month 0 31 28 31 30 31 30 31 31 30 31 30 31
eval $(echo $date|sed 's!\(....\)\(..\)\(..\)!year=\1;month=\2;day=\3!')
(( year4=year%4 ))
(( year100=year%100 ))
(( year400=year%400 ))... (7 Replies)

SLAGTS(l) ) SLAGTS(l)
NAME
SLAGTS - may be used to solve one of the systems of equations (T - lambda*I)*x = y or (T - lambda*I)'*x = y,
SYNOPSIS
SUBROUTINE SLAGTS( JOB, N, A, B, C, D, IN, Y, TOL, INFO )
INTEGER INFO, JOB, N
REAL TOL
INTEGER IN( * )
REAL A( * ), B( * ), C( * ), D( * ), Y( * )
PURPOSE
SLAGTS 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 SLAGTF. 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 SLAGTS 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) REAL array, dimension (N)
On entry, A must contain the diagonal elements of U as returned from SLAGTF.
B (input) REAL array, dimension (N-1)
On entry, B must contain the first super-diagonal elements of U as returned from SLAGTF.
C (input) REAL array, dimension (N-1)
On entry, C must contain the sub-diagonal elements of L as returned from SLAGTF.
D (input) REAL array, dimension (N-2)
On entry, D must contain the second super-diagonal elements of U as returned from SLAGTF.
IN (input) INTEGER array, dimension (N)
On entry, IN must contain details of the matrix P as returned from SLAGTF.
Y (input/output) REAL array, dimension (N)
On entry, the right hand side vector y. On exit, Y is overwritten by the solution vector x.
TOL (input/output) REAL
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.
