Top Forums Shell Programming and Scripting How to extract the individual element of array where array is assigned to another variable? Post 303045831 by sea on Tuesday 14th of April 2020 02:03:16 PM

Hi

You would have better chances with your code, if you would save lists (var="1 2 3")in the file.txt, rather than arrays.
In which case, your code would work just fine - as it is right now.

As a 2nd note, * and @ behave differently for arrays.
Though, you'll get only the first value of an array shown, with this method.

Hope this helps

NAME
Array::Diff - Find the differences between two arrays SYNOPSIS
my @old = ( 'a', 'b', 'c' ); my @new = ( 'b', 'c', 'd' ); my $diff = Array::Diff->diff( @old, @new ); $diff->count # 2 $diff->added # [ 'd' ]; $diff->deleted # [ 'a' ]; DESCRIPTION
This module compares two arrays and returns the added or deleted elements in two separate arrays. It's a simple wrapper around Algorithm::Diff. And if you need more complex array tools, check Array::Compare. METHODS
new () Create a new "Array::Diff" object. diff ( OLD, NEW ) Compute the differences between two arrays. The results are stored in the "added", "deleted", and "count" properties that may be examined using the corresponding methods. This method may be invoked as an object method, in which case it will recalculate the differences and repopulate the "count", "added", and "removed" properties, or as a static method, in which case it will return a newly-created "Array::Diff" object with the properies set appropriately. added ( [VALUES ] ) Get or set the elements present in the "NEW" array and absent in the "OLD" one at the comparison performed by the last "diff()" invocation. deleted ( [VALUES] ) Get or set the elements present in the "OLD" array and absent in the "NEW" one at the comparison performed by the last "diff()" invocation. count ( [VALUE] ) Get or set the total number of added or deleted elements at the comparison performed by the last "diff()" invocation. This count should be equal to the sum of the number of elements in the "added" and "deleted" properties. SEE ALSO
