I am creating a bash that uses perl . The below code closes before the input is entered. If I run the perl as a .pl it is fine. What am I doing wrong? Thank you .
hi!
i need to do a ksh script that uses a wile loop that is fed form below
while read line
do
some things
done < myfile
inside the while loop i need to read user input to ask the user what he wants to do, but "read" reads the file, and not the standard input
while read line
do

Hi,
The gcc compiler has warned about using gets(), so I've been trying my hand at getline.
Problem is that I've been able to read from a file, but what I really need is to read from a user's input.
I want to use getline like a scanf() command, but I can't figure what to substitute for the fp... (6 Replies)
Hiii
I wanna a read a line of text from standard input. The user enter data like this way
name phone_no month1_salary month2_salary
that is user enter the name ,phone no and salary of 2 months in a single line by giving spaces. I wanna add the 3rd and 4th fields ...ie add both... (4 Replies)
I need to write a bourne shell script (solaris 10) that accepts input from the user. The input will be a command- any command like ls/ pwd/ mv etc. After the input is read, the shell must execute the command supplied by the user.
I know we use read to play with user inputs. Just not sure how to... (2 Replies)
Hi
I am new to writing script and want to use a Bash Piped while-read and read from user input.
if something happens on server.log then do while loop or if something happend on user input then do while loop.
Pseudocode something like:
tail -n 3 -f server.log | while read serverline || read... (8 Replies)
Below is a simple script to prompt for user input while suggesting an editable default value at the prompt:

Please enter the username you would like to add:... (3 Replies)
Hi,
i am working on one automation , for that i have writing one shell program that take user input in "while read line" block. but read command is taking value that is readed by While block.

Hi,
This query is a part of a much more lengthy script.
I wish to look for all the files in a folder named "data" which in this case has two files i.e. plan.war and agent.properties. For all the files found under data I wish to ask the user as to where they wish copy the files to.
Below,... (14 Replies)
I am attempting to script the creation of MacOS installation flash media using read to allow the user to designate the name of the volume and store it in the variable VOLNAME. When I run the script, and input the name of the volume, I get the error:

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