But is there a way to do it disregarding the first column values.
If you want to disregard the first column, just print the sum:

By default, the order in which a for (i in array) loop scans an array is not defined; it is generally based upon the internal implementation of arrays inside awk.
You might have to use an indexed array to preserve the order.
HI ALL,
i have a problem when i do a sort sum with many fields.
Is there a limit for fields?
Do you know a solution?
thanks in advance.
the shell is:
# SORT1
SORT1_rcode=777
if ; then
echo "USE $DARSEQ/OTPU.FTPEPREC RECORD F,1000 " > $DARPARSRT/TPEKL508.SORT1_$$.srt

Hey,
I have a file and it has only one field. I need to calculate the sum of each filed as total.
For e.g my file is
1
2
3
4
5
I need to calculate the total sum as 15.
Please let me know how i can do it? (4 Replies)
Hi unix gurus,
I have a urgent requirement, I need to write a AWK script to compare each fields in 2 files using AWK.
Basically my output should be like this.
file1
row|num1|num2|num3
1|one|two|three
2|one|two|three
file2
row|num1|num2|num3
1|one|two|three
2|one|two|four

Hi,
I have two files formatted as following:
File 1: (user_num_ID , realID) (the NR here is 41671)

3 cust_406_4

File 2: (realID , clusterNumber) (total NR here is 1000)
cust_034_60 2
cust_406_4 3

I use the two awk scripts for comparing file1 and file2.
First awk compare $3 column:
awk -v OFS="\t" 'NR==FNR{a=$4;next}{$2=$2 "\t"(a?a:"-")}1' file1 file2Second awk compare $2 column:
awk -v OFS="\t" 'NR==FNR{a=$4;next}{$2=$2 "\t"(a?a:"-")}1' file1 file2 The only difference

In the awk below I am trying to add a penalty to a score to each matching $1 in file2 based on the sum of $3+$4 (variable TL) from file1. Then the $4 value in file1 is divided by TL and multiplied by 100 (this valvue is variable S). Finally, $2 in file2 - S gives the updated $2 result in file2.... (2 Replies)
Hi, I have two TEST files t.xyz and a.xyz which have three columns each. a.xyz have more rows than t.xyz. I will like to output rows at which $1 and $2 of t.xyz match $1 and $2 of a.xyz. Total number of output rows should be equal to that of t.xyz.
It works fine, but when I apply it to large... (6 Replies)

sgelsx.f(3) LAPACK sgelsx.f(3)NAME
sgelsx.f -
SYNOPSIS
Functions/Subroutines
subroutine sgelsx (M, N, NRHS, A, LDA, B, LDB, JPVT, RCOND, RANK, WORK, INFO)
SGELSX solves overdetermined or underdetermined systems for GE matrices
Function/Subroutine Documentation
subroutine sgelsx (integerM, integerN, integerNRHS, real, dimension( lda, * )A, integerLDA, real, dimension( ldb, * )B, integerLDB, integer,
dimension( * )JPVT, realRCOND, integerRANK, real, dimension( * )WORK, integerINFO)
SGELSX solves overdetermined or underdetermined systems for GE matrices
Purpose:
This routine is deprecated and has been replaced by routine SGELSY.
SGELSX computes the minimum-norm solution to a real linear least
squares problem:
minimize || A * X - B ||
using a complete orthogonal factorization of A. A is an M-by-N
matrix which may be rank-deficient.
Several right hand side vectors b and solution vectors x can be
handled in a single call; they are stored as the columns of the
M-by-NRHS right hand side matrix B and the N-by-NRHS solution
matrix X.
The routine first computes a QR factorization with column pivoting:
A * P = Q * [ R11 R12 ]
[ 0 R22 ]
with R11 defined as the largest leading submatrix whose estimated
condition number is less than 1/RCOND. The order of R11, RANK,
is the effective rank of A.
Then, R22 is considered to be negligible, and R12 is annihilated
by orthogonal transformations from the right, arriving at the
complete orthogonal factorization:
A * P = Q * [ T11 0 ] * Z
[ 0 0 ]
The minimum-norm solution is then
X = P * Z**T [ inv(T11)*Q1**T*B ]
[ 0 ]
where Q1 consists of the first RANK columns of Q.
Parameters:
M
M is INTEGER
The number of rows of the matrix A. M >= 0.
N
N is INTEGER
The number of columns of the matrix A. N >= 0.
NRHS
NRHS is INTEGER
The number of right hand sides, i.e., the number of
columns of matrices B and X. NRHS >= 0.
A
A is REAL array, dimension (LDA,N)
On entry, the M-by-N matrix A.
On exit, A has been overwritten by details of its
complete orthogonal factorization.
LDA
LDA is INTEGER
The leading dimension of the array A. LDA >= max(1,M).
B
B is REAL array, dimension (LDB,NRHS)
On entry, the M-by-NRHS right hand side matrix B.
On exit, the N-by-NRHS solution matrix X.
If m >= n and RANK = n, the residual sum-of-squares for
the solution in the i-th column is given by the sum of
squares of elements N+1:M in that column.
LDB
LDB is INTEGER
The leading dimension of the array B. LDB >= max(1,M,N).
JPVT
JPVT is INTEGER array, dimension (N)
On entry, if JPVT(i) .ne. 0, the i-th column of A is an
initial column, otherwise it is a free column. Before
the QR factorization of A, all initial columns are
permuted to the leading positions; only the remaining
free columns are moved as a result of column pivoting
during the factorization.
On exit, if JPVT(i) = k, then the i-th column of A*P
was the k-th column of A.
RCOND
RCOND is REAL
RCOND is used to determine the effective rank of A, which
is defined as the order of the largest leading triangular
submatrix R11 in the QR factorization with pivoting of A,
whose estimated condition number < 1/RCOND.
RANK
RANK is INTEGER
The effective rank of A, i.e., the order of the submatrix
R11. This is the same as the order of the submatrix T11
in the complete orthogonal factorization of A.
WORK
WORK is REAL array, dimension
(max( min(M,N)+3*N, 2*min(M,N)+NRHS )),
INFO
INFO is INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
