I have a large file with the first 2 characters of each line determining the type of record. type 03 being a subheader and then it will have multiple 04 records.
eg: 03,xxx,xxxx,xxxx
04,xxxxxxxxxxxxxxxxxxxxxxxxxxxx
04,xxxxxxxxxxxxxxxxxxxxxxxxxxxx
03,xxx,xxx,xxx

Hy guys, I'm having a very strange problem, every time I change the /etc/hosts file on an Ubuntu machine @ work, every time I change the line:
127.0.0.1 programmer.COMPANY
to
127.0.0.1 programmer.COMPANY programmer
It works till the next reboot, now, I have never experienced this on... (5 Replies)
Im trying to execute the below command on our server to list files and replace the newline in the file list with spaces, but the character 'n' is getting replaced with a space, is there any environment variable that needs to be set in UNIX?

Hi Gurus,
I tried FTP one file to UNIX which got values like
wel^come
If I see the content in unix, it shows like
wel^Zcome
^ coverted into ^Z (Control + Z )
Can someone please share what is happening here?
Thanks,

I have attached a file with few records. First 2 characters of each record are binary characters. I can remove it by
and it works fine. But
is behaving differently and removing more than expected characters. Can someone help me in accomplishing it through sed? Thanks in advance. (13 Replies)
I have two servers on same domain. one can nslookup other cannot
Psu100 can lookup to psu000, psu010 & psu011
Psu110 can NOT lookup to psu000, psu010 & psu011
I verified resolv.conf entries on both psu000 and psu010 and it contains both name servers (10.200.10.21 & 10.200.11.22).I am... (1 Reply)
Hi,
I need to count number of '$' symbol in a file and assign it to a variable.
I am using below command.
grep -c '\$' inputfile
O/p:
10359
Its giving correct o/p but when I am assigning the same to a variable its giving completely different o/p.

Hello.
During the holidays I've been developing an application on my desktop computer at home.
I setup a repository on github, so when I got back to work I cloned the repo to my laptop.
It wouldn't work.
The app is comprised of a client and a server, strangely enough the server would segfault... (10 Replies)
Hi,
Immediate help on below will be appreciated.
I have to read a file (max of 10MB) which will have no new line characters, i.e. data in single line. and have to inster '\n' at every 100 characters. and if record starts with 'BUCA' then need to pick value of length 10 at position 71 and... (7 Replies)

SYNOPSIS
Functions/Subroutines
subroutine dlagts (JOB, N, A, B, C, D, IN, Y, TOL, INFO)
DLAGTS
Function/Subroutine Documentation
subroutine dlagts (integerJOB, integerN, double precision, dimension( * )A, double precision, dimension( * )B, double precision, dimension( *
)C, double precision, dimension( * )D, integer, dimension( * )IN, double precision, dimension( * )Y, double precisionTOL, integerINFO)
DLAGTS
Purpose:
DLAGTS may be used to solve one of the systems of equations
(T - lambda*I)*x = y or (T - lambda*I)**T*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.
Parameters:
JOB
JOB is 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 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.
= 2: The equations (T - lambda*I)**Tx = y are to be solved,
but diagonal elements of U are not to be perturbed.
= -2: The equations (T - lambda*I)**Tx = 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
N is INTEGER
The order of the matrix T.
A
A is DOUBLE PRECISION array, dimension (N)
On entry, A must contain the diagonal elements of U as
returned from DLAGTF.
B
B is DOUBLE PRECISION array, dimension (N-1)
On entry, B must contain the first super-diagonal elements of
U as returned from DLAGTF.
C
C is DOUBLE PRECISION array, dimension (N-1)
On entry, C must contain the sub-diagonal elements of L as
returned from DLAGTF.
D
D is DOUBLE PRECISION array, dimension (N-2)
On entry, D must contain the second super-diagonal elements
of U as returned from DLAGTF.
IN
IN is INTEGER array, dimension (N)
On entry, IN must contain details of the matrix P as returned
from DLAGTF.
Y
Y is DOUBLE PRECISION array, dimension (N)
On entry, the right hand side vector y.
On exit, Y is overwritten by the solution vector x.
TOL
TOL is 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
INFO is INTEGER
= 0 : successful exit
.lt. 0: if INFO = -i, the i-th argument had an illegal value
.gt. 0: overflow would occur when computing the INFO(th)
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.
