If you want to extract integers from a string, one way is to use regular expressions (perlre): `use warnings; use strict; use Data::Dumper; my $str = '"[1,2]"'; my @nums = $str =~ /(\d+)/g; print Dumper(\@nums); __END__ $VAR1 = [ '1', '2' ];` [download] See also: perlintro perlretut Perl Idioms Explained - @ary = $str =~ m/(stuff)/g	[reply] [d/l]

Splitting a string into parts. There is a function for that called split `$string=~s/\[(.*)\]/$1/; #removing [] @numbers= split /,/,$string;` [download]	[reply] [d/l]

Some, untested, ways: `@array = $str =~ /[^][,]/g; @array = $str =~ /[0-9]/g; @array = split ',', substr $str, 1, -1; @array = do {my %h = split //, $str; grep {defined} values %h};` [download] It's hard to determine from a single, simple, example what you really want.	[reply] [d/l]

I don't recommend doing this (other answers were safer) but for the sake of completeness: `perl -le 'my $aref = eval "[1,2]"; print join("+", @{$aref})' 1+2` [download]	[reply] [d/l]

Assuming you're the same Anonymous Monk as in the previous threads, why don't you generate a proper array ref in the first place? Perl 6 - second systems done right	[reply]

I think the best way is to use regular expressions (strongest and useful characteristic in perl) or even sprintf. I'll recomend you to take a look at PerlRE first	[reply]
