Perfect solution if you don't care for the order of fields. If you do, it may disappoint you, as the order of elements supplied is not granted in a for (i in a) construct. Then you may want to try
The delete array statement is NOT supported in all awks, fallback to previous proposal , then. This proposal is clumsier than the previous solution, but it keeps the order of fields, suppressing their later occurrences.
How can i read all the unique words in a file, i used -
cat comment_file.txt | /usr/xpg6/bin/tr -sc 'A-Za-z' '/012'
and
cat comment_file.txt | /usr/xpg6/bin/tr -sdc 'A-Za-z' '/012'
but they didnt worked..... (5 Replies)
Hello all
i know it is pretty hard one but you will manage it all
after noticing and calculating i find a rhythm for the file i want to edit
to copy the last 12 characters in line but the problem is to add after first 25 characters in same line
in other way too copy the last 12 characters... (10 Replies)
Hello, I tried to count all unique words of all files in one folder and its subfolders. Can anybody say me, why this doesnt work:
ls| find -d | cat | tr "\ " "\n"| uniq -u | wc -l
???
Cat writes only the names of those files, but not the wors, which should be in them.
Thanks for any advice.

I am having a file with duplicate words how can I eliminate them
ant,bat
bat,cat
cat a.txt | grep -bat | awk '{print $1}'
expecting o/p as ant,bat,cat
How can I display the output as ant,bat,cat in a single line and no duplicates exists. (2 Replies)
Hi All
I have to search servers name say like 1000+ "unique names" line by line in child.txt files in another file that is a master file where all server present say "master.txt",if child.txt's server name matches with master files then it print yes else no with server name. (4 Replies)
Hello,
I have a dictionary which I am building for the Open Source Community. The data structure is as under
HEADWORD=PARTOFSPEECH=ENGLISH MEANING
as shown in the example below
अ=m=Prefix signifying negation.

Hi All,
I need one help to replace particular words in file based on if finds another words in that file .
i.e.
my self is peter@king.

CPTSV(l) ) CPTSV(l)
NAME
CPTSV - compute the solution to a complex system of linear equations A*X = B, where A is an N-by-N Hermitian positive definite tridiagonal
matrix, and X and B are N-by-NRHS matrices
SYNOPSIS
SUBROUTINE CPTSV( N, NRHS, D, E, B, LDB, INFO )
INTEGER INFO, LDB, N, NRHS
REAL D( * )
COMPLEX B( LDB, * ), E( * )
PURPOSE
CPTSV computes the solution to a complex system of linear equations A*X = B, where A is an N-by-N Hermitian positive definite tridiagonal
matrix, and X and B are N-by-NRHS matrices. A is factored as A = L*D*L**H, and the factored form of A is then used to solve the system of
equations.
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/output) REAL array, dimension (N)
On entry, the n diagonal elements of the tridiagonal matrix A. On exit, the n diagonal elements of the diagonal matrix D from the
factorization A = L*D*L**H.
E (input/output) COMPLEX array, dimension (N-1)
On entry, the (n-1) subdiagonal elements of the tridiagonal matrix A. On exit, the (n-1) subdiagonal elements of the unit bidiago-
nal factor L from the L*D*L**H factorization of A. E can also be regarded as the superdiagonal of the unit bidiagonal factor U
from the U**H*D*U factorization of A.
B (input/output) COMPLEX array, dimension (LDB,NRHS)
On entry, the N-by-NRHS right hand side matrix B. On exit, if INFO = 0, the N-by-NRHS solution matrix X.
LDB (input) INTEGER
The leading dimension of the array B. LDB >= max(1,N).
INFO (output) INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
> 0: if INFO = i, the leading minor of order i is not positive definite, and the solution has not been computed. The factoriza-
tion has not been completed unless i = N.
