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

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.

How to replace peter to sham if it finds @king in any line of that file.
Please help me... (8 Replies)

zgtsv.f(3) LAPACK zgtsv.f(3)NAME
zgtsv.f -
SYNOPSIS
Functions/Subroutines
subroutine zgtsv (N, NRHS, DL, D, DU, B, LDB, INFO)
ZGTSV computes the solution to system of linear equations A * X = B for GT matrices
Function/Subroutine Documentation
subroutine zgtsv (integerN, integerNRHS, complex*16, dimension( * )DL, complex*16, dimension( * )D, complex*16, dimension( * )DU, complex*16,
dimension( ldb, * )B, integerLDB, integerINFO)
ZGTSV computes the solution to system of linear equations A * X = B for GT matrices
Purpose:
ZGTSV solves the equation
A*X = B,
where A is an N-by-N tridiagonal matrix, by Gaussian elimination with
partial pivoting.
Note that the equation A**T *X = B may be solved by interchanging the
order of the arguments DU and DL.
Parameters:
N
N is INTEGER
The order of the matrix A. N >= 0.
NRHS
NRHS is INTEGER
The number of right hand sides, i.e., the number of columns
of the matrix B. NRHS >= 0.
DL
DL is COMPLEX*16 array, dimension (N-1)
On entry, DL must contain the (n-1) subdiagonal elements of
A.
On exit, DL is overwritten by the (n-2) elements of the
second superdiagonal of the upper triangular matrix U from
the LU factorization of A, in DL(1), ..., DL(n-2).
D
D is COMPLEX*16 array, dimension (N)
On entry, D must contain the diagonal elements of A.
On exit, D is overwritten by the n diagonal elements of U.
DU
DU is COMPLEX*16 array, dimension (N-1)
On entry, DU must contain the (n-1) superdiagonal elements
of A.
On exit, DU is overwritten by the (n-1) elements of the first
superdiagonal of U.
B
B is COMPLEX*16 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
LDB is INTEGER
The leading dimension of the array B. LDB >= max(1,N).
INFO
INFO is INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
> 0: if INFO = i, U(i,i) is exactly zero, and the solution
has not been computed. The factorization has not been
completed unless i = N.
