awk or grep to search one column and output the other
Hello,
it would be great if someone can help me with the following:
I want to search for the rows from fileA in column 1 of fileB and output column 2 of fileB if found in fileC. In the moment I search within the complete file. How can I change the code so only column 1 is searched?

Hi,
I have a file that has many columns. Let us say "Employee_number" "Employee_name" "Salary". I want to display all entries in a column by giving all or part of the column name. For example if I input "name" I want all the employee names printed. Is it possible to do this in a simple manner... (2 Replies)

Hello,
Similar question to my previous posts. I am sorry for the trouble...
Just checked my old threads but I can not implement any solution into this case..
My aim is to grab each line in fileA, check it in fileB and merge with fileC (tab separated) in corresponding line as given below:

SGBEQU(l) ) SGBEQU(l)
NAME
SGBEQU - compute row and column scalings intended to equilibrate an M-by-N band matrix A and reduce its condition number
SYNOPSIS
SUBROUTINE SGBEQU( M, N, KL, KU, AB, LDAB, R, C, ROWCND, COLCND, AMAX, INFO )
INTEGER INFO, KL, KU, LDAB, M, N
REAL AMAX, COLCND, ROWCND
REAL AB( LDAB, * ), C( * ), R( * )
PURPOSE
SGBEQU computes row and column scalings intended to equilibrate an M-by-N band matrix A and reduce its condition number. R returns the row
scale factors and C the column scale factors, chosen to try to make the largest element in each row and column of the matrix B with ele-
ments B(i,j)=R(i)*A(i,j)*C(j) have absolute value 1.
R(i) and C(j) are restricted to be between SMLNUM = smallest safe number and BIGNUM = largest safe number. Use of these scaling factors is
not guaranteed to reduce the condition number of A but works well in practice.
ARGUMENTS
M (input) INTEGER
The number of rows of the matrix A. M >= 0.
N (input) INTEGER
The number of columns of the matrix A. N >= 0.
KL (input) INTEGER
The number of subdiagonals within the band of A. KL >= 0.
KU (input) INTEGER
The number of superdiagonals within the band of A. KU >= 0.
AB (input) REAL array, dimension (LDAB,N)
The band matrix A, stored in rows 1 to KL+KU+1. The j-th column of A is stored in the j-th column of the array AB as follows:
AB(ku+1+i-j,j) = A(i,j) for max(1,j-ku)<=i<=min(m,j+kl).
LDAB (input) INTEGER
The leading dimension of the array AB. LDAB >= KL+KU+1.
R (output) REAL array, dimension (M)
If INFO = 0, or INFO > M, R contains the row scale factors for A.
C (output) REAL array, dimension (N)
If INFO = 0, C contains the column scale factors for A.
ROWCND (output) REAL
If INFO = 0 or INFO > M, ROWCND contains the ratio of the smallest R(i) to the largest R(i). If ROWCND >= 0.1 and AMAX is neither
too large nor too small, it is not worth scaling by R.
COLCND (output) REAL
If INFO = 0, COLCND contains the ratio of the smallest C(i) to the largest C(i). If COLCND >= 0.1, it is not worth scaling by C.
AMAX (output) REAL
Absolute value of largest matrix element. If AMAX is very close to overflow or very close to underflow, the matrix should be
scaled.
INFO (output) INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
> 0: if INFO = i, and i is
<= M: the i-th row of A is exactly zero
> M: the (i-M)-th column of A is exactly zero
