The solution from NetWallah looks fine to me.

I added a line to make it clear that the foreach() in my code does use an @variable. And I showed the idioms for deleting whitespace before and after a "line". Anyway, very happy that you can proceed further!

#!/usr/bin/perl -w
use strict;

my $line = "this- is-aline  - one-  two  ";
my @array = split (/-/,$line);
foreach (@array)
{
   s/\s+$//g;  #throw away tailing whitespace
   s/^\s+//g;  #throw away leading whitespace
   print "$_\n";
}
__END__
PRINTS:
this
is
aline
one
two

If you change the split regex to allow optional spaces around the hyphen and prepend and append hyphens to the text you can avoid the space trimming substitutions. You do have to shift away the empty first element though.

$ perl -le '
> $str = q{  this- is-aline  - one-  two  };
> @arr = split m{\s*-\s*}, qq{-$str-};
> shift @arr;
> print qq{->$_<-} for @arr;'
->this<-
->is<-
->aline<-
->one<-
->two<-

I hope this is of interest.
