Hi,
can we use arrays in shell script?
I have this so far:
#!/bin/sh
isql -Usa -P -S DBSERVER -o output << EOF
sp_transactions "state", "prepared", "xactname"
go
/
EOF
the file 'output'' will be have many entries and I want to caputre the transaction names only: grep 000 output works... (3 Replies)

I have to perform a pattern replacement on each file present in abc array accept the files i have in xyz array. and i am doing... (4 Replies)
Ok so spaces separate elements. What if you wanted an element to have a space in it?
For instance:
nums="one two three and a half"
where "three and a half" is THE SAME element? (3 Replies)
I have defined an array like this:

lfind
LSEARCH(3) BSD Library Functions Manual LSEARCH(3)NAME
lsearch, lfind -- linear search and append
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <search.h>
void *
lsearch(const void *key, void *base, size_t *nelp, size_t width, int (*compar)(const void *, const void *));
void *
lfind(const void *key, const void *base, size_t *nelp, size_t width, int (*compar)(const void *, const void *));
DESCRIPTION
The lsearch() and lfind() functions walk linearly through an array and compare each element with the one to be sought using a supplied com-
parison function.
The key argument points to an element that matches the one that is searched. The array's address in memory is denoted by the base argument.
The width of one element (i.e., the size as returned by sizeof()) is passed as the width argument. The number of valid elements contained in
the array (not the number of elements the array has space reserved for) is given in the integer pointed to by nelp. The compar argument
points to a function which compares its two arguments and returns zero if they are matching, and non-zero otherwise.
If no matching element was found in the array, lsearch() copies key into the position after the last element and increments the integer
pointed to by nelp.
RETURN VALUES
The lsearch() and lfind() functions return a pointer to the first element found. If no element was found, lsearch() returns a pointer to the
newly added element, whereas lfind() returns NULL. Both functions return NULL if an error occurs.
EXAMPLES
#include <search.h>
#include <stdio.h>
#include <stdlib.h>
static int
element_compare(const void *p1, const void *p2)
{
int left = *(const int *)p1;
int right = *(const int *)p2;
return (left - right);
}
int
main(int argc, char **argv)
{
const int array[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
size_t element_size = sizeof(array[0]);
size_t array_size = sizeof(array) / element_size;
int key;
void *element;
printf("Enter a number: ");
if (scanf("%d", &key) != 1) {
printf("Bad input0);
return (EXIT_FAILURE);
}
element = lfind(&key, array, &array_size, element_size,
element_compare);
if (element != NULL)
printf("Element found: %d0, *(int *)element);
else
printf("Element not found0);
return (EXIT_SUCCESS);
}
