Hi,
I am a new learner of Unix. I am currently working on a Solaris 8 machine. Earlier, when I use 'cd <folder name>' command, I am not only able to change the folder but also able to see the contents of the folder as if a 'ls -lt' command was executed. However, since a week, suddenly this... (3 Replies)
I am using AIX and ksh.
I need to display the contents of a file that has a pid (process id). Because the file is open, it doesn't have the line feed or new line, so for some reason if I do this:
`cat $pid` , where $pid is the name of the fully qualified file, it displays

Hi All,
I'm trying to figure out which are the trusted-ips and which are not using a script file.. I have a file named 'ip-list.txt' which contains some ip addresses and another file named 'trusted-ip-list.txt' which also contains some ip addresses. I want to read a line from... (4 Replies)
Hi All
I have multiple arrays like below.
set -A val1 1 2 4 5

slarra.f(3) LAPACK slarra.f(3)NAME
slarra.f -
SYNOPSIS
Functions/Subroutines
subroutine slarra (N, D, E, E2, SPLTOL, TNRM, NSPLIT, ISPLIT, INFO)
SLARRA
Function/Subroutine Documentation
subroutine slarra (integerN, real, dimension( * )D, real, dimension( * )E, real, dimension( * )E2, realSPLTOL, realTNRM, integerNSPLIT,
integer, dimension( * )ISPLIT, integerINFO)
SLARRA
Purpose:
Compute the splitting points with threshold SPLTOL.
SLARRA sets any "small" off-diagonal elements to zero.
Parameters:
N
N is INTEGER
The order of the matrix. N > 0.
D
D is REAL array, dimension (N)
On entry, the N diagonal elements of the tridiagonal
matrix T.
E
E is REAL array, dimension (N)
On entry, the first (N-1) entries contain the subdiagonal
elements of the tridiagonal matrix T; E(N) need not be set.
On exit, the entries E( ISPLIT( I ) ), 1 <= I <= NSPLIT,
are set to zero, the other entries of E are untouched.
E2
E2 is REAL array, dimension (N)
On entry, the first (N-1) entries contain the SQUARES of the
subdiagonal elements of the tridiagonal matrix T;
E2(N) need not be set.
On exit, the entries E2( ISPLIT( I ) ),
1 <= I <= NSPLIT, have been set to zero
SPLTOL
SPLTOL is REAL
The threshold for splitting. Two criteria can be used:
SPLTOL<0 : criterion based on absolute off-diagonal value
SPLTOL>0 : criterion that preserves relative accuracy
TNRM
TNRM is REAL
The norm of the matrix.
NSPLIT
NSPLIT is INTEGER
The number of blocks T splits into. 1 <= NSPLIT <= N.
ISPLIT
ISPLIT is INTEGER array, dimension (N)
The splitting points, at which T breaks up into blocks.
The first block consists of rows/columns 1 to ISPLIT(1),
the second of rows/columns ISPLIT(1)+1 through ISPLIT(2),
etc., and the NSPLIT-th consists of rows/columns
ISPLIT(NSPLIT-1)+1 through ISPLIT(NSPLIT)=N.
INFO
INFO is INTEGER
= 0: successful exit
