You do it straightforward. An array is just another variable after all and variables in shell scripts can be created just by using them.
Alas you haven't said which shell you are using, so as your penance for omitting this vital information i just suppose you are using Korn shell (ksh) and if you don't you will have to translate my solution to your shell yourself. ;-))
Suppose the following input file. We want all the lines "data=<value>" and store the "<value>" in an indexed array (1-based):
Now the script, which will read it and put the content into an array, like stated above:
Hi,
Is is possible to get the value using shell script?
x=1
y1 = 10
y2 = 15
y3 = 7
echo $y$x is giving y1 (variable name)
but I need the value of y1 (i.e. 10 dynamically)
Is there any solution?
if so, please mail me at kkodava@maxis.com.my

Now I want to store those values into an array. How can be done this ?? (3 Replies)
I know there are caveats about using read in pipelines because read is treated by a subshell. I know this but I can't think of any way to accomplish this regardless, I'm still a rookie.
I hope somebody will be able to interpret what it is that I'm trying to accomplish and correct me.

array
ARRAY(3) 1 ARRAY(3)array - Create an arraySYNOPSIS
array array ([mixed $...])
DESCRIPTION
Creates an array. Read the section on the array type for more information on what an array is.
PARAMETERS
o $...
- Syntax "index => values", separated by commas, define index and values. index may be of type string or integer. When index is
omitted, an integer index is automatically generated, starting at 0. If index is an integer, next generated index will be the big-
gest integer index + 1. Note that when two identical index are defined, the last overwrite the first. Having a trailing comma
after the last defined array entry, while unusual, is a valid syntax.
RETURN VALUES
Returns an array of the parameters. The parameters can be given an index with the => operator. Read the section on the array type for more
information on what an array is.
EXAMPLES
The following example demonstrates how to create a two-dimensional array, how to specify keys for associative arrays, and how to skip-and-
continue numeric indices in normal arrays.
Example #1
array(3) example
<?php
$fruits = array (
"fruits" => array("a" => "orange", "b" => "banana", "c" => "apple"),
"numbers" => array(1, 2, 3, 4, 5, 6),
"holes" => array("first", 5 => "second", "third")
);
?>
Example #2
Automatic index with array(3)
<?php
$array = array(1, 1, 1, 1, 1, 8 => 1, 4 => 1, 19, 3 => 13);
print_r($array);
?>
The above example will output:
Array
(
[0] => 1
[1] => 1
[2] => 1
[3] => 13
[4] => 1
[8] => 1
[9] => 19
)
Note that index '3' is defined twice, and keep its final value of 13. Index 4 is defined after index 8, and next generated index (value
19) is 9, since biggest index was 8.
This example creates a 1-based array.
Example #3
1-based index with array(3)
<?php
$firstquarter = array(1 => 'January', 'February', 'March');
print_r($firstquarter);
?>
The above example will output:
Array
(
[1] => January
[2] => February
[3] => March
)
As in Perl, you can access a value from the array inside double quotes. However, with PHP you'll need to enclose your array between curly
braces.
Example #4
Accessing an array inside double quotes
<?php
$foo = array('bar' => 'baz');
echo "Hello {$foo['bar']}!"; // Hello baz!
?>
NOTES
Note
array(3) is a language construct used to represent literal arrays, and not a regular function.
