I have three different files about a warehouse's stock status.
Each file shows storage locations, stored product names, quantity of the part and at last column, its price. When there is a change in price, I open those files one by one, search related product name at each row and change the price manually.
What I would like to have is a a script to make the task easier: It will ask me to enter which product name I am looking for. When I enter the product name in terminal panel, it will ask me the second question, the new price. When I enter new price in same format, it will replace the old one by the new one in all three files.
Here are my sample files:
database1.txt
database2.txt database3.txt
I am not sure if this question should be placed under "shell script" topic.
I would appreciate if you could help me.
thanks in advance
Boris

DLAUU2(l) ) DLAUU2(l)
NAME
DLAUU2 - compute the product U * U' or L' * L, where the triangular factor U or L is stored in the upper or lower triangular part of the
array A
SYNOPSIS
SUBROUTINE DLAUU2( UPLO, N, A, LDA, INFO )
CHARACTER UPLO
INTEGER INFO, LDA, N
DOUBLE PRECISION A( LDA, * )
PURPOSE
DLAUU2 computes the product U * U' or L' * L, where the triangular factor U or L is stored in the upper or lower triangular part of the
array A. If UPLO = 'U' or 'u' then the upper triangle of the result is stored, overwriting the factor U in A.
If UPLO = 'L' or 'l' then the lower triangle of the result is stored, overwriting the factor L in A.
This is the unblocked form of the algorithm, calling Level 2 BLAS.
ARGUMENTS
UPLO (input) CHARACTER*1
Specifies whether the triangular factor stored in the array A is upper or lower triangular:
= 'U': Upper triangular
= 'L': Lower triangular
N (input) INTEGER
The order of the triangular factor U or L. N >= 0.
A (input/output) DOUBLE PRECISION array, dimension (LDA,N)
On entry, the triangular factor U or L. On exit, if UPLO = 'U', the upper triangle of A is overwritten with the upper triangle of
the product U * U'; if UPLO = 'L', the lower triangle of A is overwritten with the lower triangle of the product L' * L.
LDA (input) INTEGER
The leading dimension of the array A. LDA >= max(1,N).
INFO (output) INTEGER
= 0: successful exit
< 0: if INFO = -k, the k-th argument had an illegal value
