perl sort
Hi all,

Say i have a array

Code:
@array=("abc,"a",ab");

I would like to sort them according to the length.

Any idea? thanks in advanced.

i tried below code, but not work.

Code:
sub sort_fun{
 if (length shift(@_) >= length shift(@_) ){
        return 1;
 }
 else{
        return 0;
 }
}

print join (", ",sort{sort_fun($a,$b)} ("abc","a","ab") ."\n";

Code:
my @array = qw(abc a ab);
@array = sort {length $a <=> length $b} @array;
print "$_\n" for @array;
