Tricky situation getting IP address
Hi,
I have a multihomed system HP-UX with two NIC cards having IP address 10.9.0.13 & 10.9.0.45
I have two weblogic servers running one listening on "10.9.0.13" and the other on "10.9.0.45"
Given a PID how is it possible to extract the IP Address that the weblogic server is using and store it in a bash variable "myh" ?
I am looking for a solution for HP-UX and then for all Linux and Unix systems so if you could share some solution for HP-UX and others as well.

Hi,
I'm looking for someone who can think in sed. Basically, I need the trailing characters on every line in a file to be deleted. These characters are all in capitals, and always follow a number, but they often vary in number
For instance, on the line:

Hi
All,
How can you sort a file that is doubled space ( where even number lines are blank lines) and still preserves the blank lines?
You can use grep,sed and regular expression.
Thanks

sptrfs
SPTRFS(l) ) SPTRFS(l)
NAME
SPTRFS - improve the computed solution to a system of linear equations when the coefficient matrix is symmetric positive definite and
tridiagonal, and provides error bounds and backward error estimates for the solution
SYNOPSIS
SUBROUTINE SPTRFS( N, NRHS, D, E, DF, EF, B, LDB, X, LDX, FERR, BERR, WORK, INFO )
INTEGER INFO, LDB, LDX, N, NRHS
REAL B( LDB, * ), BERR( * ), D( * ), DF( * ), E( * ), EF( * ), FERR( * ), WORK( * ), X( LDX, * )
PURPOSE
SPTRFS improves the computed solution to a system of linear equations when the coefficient matrix is symmetric positive definite and tridi-
agonal, and provides error bounds and backward error estimates for the solution.
ARGUMENTS
N (input) INTEGER
The order of the matrix A. N >= 0.
NRHS (input) INTEGER
The number of right hand sides, i.e., the number of columns of the matrix B. NRHS >= 0.
D (input) REAL array, dimension (N)
The n diagonal elements of the tridiagonal matrix A.
E (input) REAL array, dimension (N-1)
The (n-1) subdiagonal elements of the tridiagonal matrix A.
DF (input) REAL array, dimension (N)
The n diagonal elements of the diagonal matrix D from the factorization computed by SPTTRF.
EF (input) REAL array, dimension (N-1)
The (n-1) subdiagonal elements of the unit bidiagonal factor L from the factorization computed by SPTTRF.
B (input) REAL array, dimension (LDB,NRHS)
The right hand side matrix B.
LDB (input) INTEGER
The leading dimension of the array B. LDB >= max(1,N).
X (input/output) REAL array, dimension (LDX,NRHS)
On entry, the solution matrix X, as computed by SPTTRS. On exit, the improved solution matrix X.
LDX (input) INTEGER
The leading dimension of the array X. LDX >= max(1,N).
FERR (output) REAL array, dimension (NRHS)
The forward error bound for each solution vector X(j) (the j-th column of the solution matrix X). If XTRUE is the true solution
corresponding to X(j), FERR(j) is an estimated upper bound for the magnitude of the largest element in (X(j) - XTRUE) divided by
the magnitude of the largest element in X(j).
BERR (output) REAL array, dimension (NRHS)
The componentwise relative backward error of each solution vector X(j) (i.e., the smallest relative change in any element of A or B
that makes X(j) an exact solution).
WORK (workspace) REAL array, dimension (2*N)
INFO (output) INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
PARAMETERS
ITMAX is the maximum number of steps of iterative refinement.
