A file contains one name per line, such as:
john doe
jack bruce
nancy smith
sam riley
When I 'cat' the file, the white space is treated as a new line. For example
list=`(cat /path/to/file.txt)`
for items in $list
do
echo $items
done
I get:
john

Hello!
There is a text file, that contains hierarchy of menues, like:
Aaaaa->Bbbbb
Aaaaa->Cccc
Aaaaa-> {spaces} Ddddd (it means that the full path is Aaaaa->Cccc->Ddddd )
Aaaaa-> {more spaces} Eeeee (it means that the full path is Aaaaa->Cccc->Ddddd->Eeeee )
Fffffff->Ggggg... (1 Reply)
I'm trying to strip any garbage that may be at the end of my text file and that part is working. The problem only seems to be with the really long lines in the file. When the head command is executed I am directing the output to a new file. The new file always get a null in the 4096 position but... (2 Replies)
Hi,
I have to perform an iterative function on a set of 10 files. After the first round the output files are named differently than the input files.
examples
input file name = xxxx1.yyy
output file name = xxxx1_0001.yyy
I need to rename all of the output files to the original input... (5 Replies)

Hi ALL,
I am presently using perl script mukesh.pl I just want to catch its output into another text file .
So I am using > File.txt .
I am getting output but i want the whole processing of the script into that file please let me know .
Thanks in advance

Hello,
I extracted a list of files in a directory with the command ls . However this is not my computer, so the ls functionality has been revamped so that it gives the filesizes in front like this :
This is the output of ls command : I stored the output in a file filelist

Hello,
I want to grep a log ("server.log") for words in a separate file ("white-list.txt") and generate a separate log file containing each line that uses a word from the "white-list.txt" file.
Putting that in bullet points:
Search through "server.log" for lines that contain any word... (15 Replies)

sdisna
sdisna.f(3) LAPACK sdisna.f(3)NAME
sdisna.f -
SYNOPSIS
Functions/Subroutines
subroutine sdisna (JOB, M, N, D, SEP, INFO)
SDISNA
Function/Subroutine Documentation
subroutine sdisna (characterJOB, integerM, integerN, real, dimension( * )D, real, dimension( * )SEP, integerINFO)
SDISNA
Purpose:
SDISNA computes the reciprocal condition numbers for the eigenvectors
of a real symmetric or complex Hermitian matrix or for the left or
right singular vectors of a general m-by-n matrix. The reciprocal
condition number is the 'gap' between the corresponding eigenvalue or
singular value and the nearest other one.
The bound on the error, measured by angle in radians, in the I-th
computed vector is given by
SLAMCH( 'E' ) * ( ANORM / SEP( I ) )
where ANORM = 2-norm(A) = max( abs( D(j) ) ). SEP(I) is not allowed
to be smaller than SLAMCH( 'E' )*ANORM in order to limit the size of
the error bound.
SDISNA may also be used to compute error bounds for eigenvectors of
the generalized symmetric definite eigenproblem.
Parameters:
JOB
JOB is CHARACTER*1
Specifies for which problem the reciprocal condition numbers
should be computed:
= 'E': the eigenvectors of a symmetric/Hermitian matrix;
= 'L': the left singular vectors of a general matrix;
= 'R': the right singular vectors of a general matrix.
M
M is INTEGER
The number of rows of the matrix. M >= 0.
N
N is INTEGER
If JOB = 'L' or 'R', the number of columns of the matrix,
in which case N >= 0. Ignored if JOB = 'E'.
D
D is REAL array, dimension (M) if JOB = 'E'
dimension (min(M,N)) if JOB = 'L' or 'R'
The eigenvalues (if JOB = 'E') or singular values (if JOB =
'L' or 'R') of the matrix, in either increasing or decreasing
order. If singular values, they must be non-negative.
SEP
SEP is REAL array, dimension (M) if JOB = 'E'
dimension (min(M,N)) if JOB = 'L' or 'R'
The reciprocal condition numbers of the vectors.
INFO
INFO is INTEGER
= 0: successful exit.
< 0: if INFO = -i, the i-th argument had an illegal value.
