Hi
I m having ifconfig -a o/p like
sbanlab1:ksh# ifconfig -a | egrep "flags|inet" | awk -F' ' '{print $1,$2}'

Hi,
I've a txt file which contains the following kind of listed data
18971 ./aosrp18.r
15340 ./aosrp12.r
22996 ./aosrp08.r
17125 ./aosrp06.r
I'm trying to get rid of the ./ in the file and have tried the following with sed but I'm not getting the correct result... I'm not sure what way... (7 Replies)
So, I want to read line-by-line a text file with unknown number of files....
So:
a=1
b=1
while ; do
b=`sed -n '$ap' test`
a=`expr $a + 1`
$here do something with b etc
done
the problem is that sed does not seem to recognise the $a, even when trying
sed -n ' $a p'
So, I cannot read... (3 Replies)
Hi,
I have a file that contains whitespaces with spaces and spaces and tabs on each line and am wanting to remove the whitespaces. My version of sed is one that does not recognize \t etc.
The sed and awk one-liners below that I found via Google both does not work.
So my next best... (3 Replies)

Hi All,
I have 4 big files which contains one big line containing formatted character records, I need to format each file in such way that each File will have 95 Characters per line. Last line of each file will have newline character at end.
Before:-

I have a char* str. Suppose
str="medium";
I want to check if str has "=" as first non blank position, if it exists, I want to remove it
Currently I am checking using
if (optarg == '=') cout << "Found =" << endl; (2 Replies)
Edit: Figured it out. Close the thread please.

Hi Gurus,
I need separate one file which is one huge line to mutiple line.
file like
abcd # bcd # def # fge # ged
I want to get
abcd
bcd
def
fge
ged
Thanks in advance (4 Replies)
So given filenames of varying lengths, I was wondering how I would remove or modify appended timestamps of the current date DD-MM-YY.
So say:
test_DD-MM-YY.txt
coolbeans_DD-MM-YY.pdf
And what I expect the output to be:
test.txt
coolbeans.pdf
Thanks :) (2 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.
