Here is an example how you could cycle and compare array elements (example with integers) and print only those from array 1, which are not in array 2:
Code:
$ cat ./mach.ksh
#!/usr/bin/ksh
set -A ARR1 4 1 3 2
set -A ARR2 5 6 2 7 4 8
MAX=$((${#ARR2[*]}-1))
for a in ${ARR1[*]}; do
COUNT=0
set -A HITS
for b in ${ARR2[*]}; do
(( $a != $b )) && \
HITS[$COUNT]=$a && \
let COUNT+=1
done
(( ${#HITS[*]} != $MAX )) && \
print ${HITS[0]}
unset HITS
done
exit 0
$ ./mach.ksh

Maybe other people have more efficient algorithm to do this which would be interessting for me too.
If you have 2 files with the lists of files you might want to compare, a grep -f file1 file2 or grep -vf file1 file2 might be more efficient than my example.

Hi there all,
I am having a question.
Is it posible to compare elements of 2 different arrays?
For example I got
Array 1 | Array 2
123_abc | 123_bcd
123_bcd | 234_bcd
234_abc | 567_abc
234_bcd | 123_abc
than the match is
123_abc & 234_bcd and non of the others.
So... (3 Replies)
Hello,
Let's say that we have the two following arrays
@array1=
@array2=
Is there any easy way to compare these two arrays and print the values that exist in array1 and not in array2 and the values that exist in array2 and not in array1?

class::makemethods::utility::ref
MakeMethods::Utility::Ref(3pm) User Contributed Perl Documentation MakeMethods::Utility::Ref(3pm)NAME
Class::MakeMethods::Utility::Ref - Deep copying and comparison
SYNOPSIS
use Class::MakeMethods::Utility::Ref qw( ref_clone ref_compare );
$deep_copy = ref_clone( $original );
$positive_zero_or_negative = ref_compare( $item_a, $item_b );
DESCRIPTION
This module provides utility functions to copy and compare arbitrary references, including full traversal of nested data structures.
REFERENCE
The following functions are provided:
ref_clone()
Make a recursive copy of a reference.
ref_compare()
Attempt to recursively compare two references.
If they are not the same, try to be consistent about returning a positive or negative number so that it can be used for sorting. The sort
order is kinda arbitrary.
SEE ALSO
See Class::MakeMethods for general information about this distribution.
See Ref for the original version of the clone and compare functions used above.
See Clone (v0.09 on CPAN as of 2000-09-21) for a clone method with an XS implementation.
The Perl6 RFP #67 proposes including clone functionality in the core.
See Data::Compare (v0.01 on CPAN as of 1999-04-24) for a Compare method which checks two references for similarity, but it does not provide
positive/negative values for ordering purposes.
