By the way, it's =s when you pass a reference to an array, and =s@ when you pass a reference to a scalar.

Both seem to work and do what I want. Is there any particular reason to choose one over the other?

$ cat test-gol.pl #!/usr/bin/perl use Getopt::Long qw/:config pass_through/; my ($array, @array); # option names are: [sa][nw] s=scalar, a=array n=no '@', w=with '@' GetOptions( 'sn=s' => \$array ) or die 'options'; print "Scalar @$array\n"; undef $array; GetOptions( 'sw=s@' => \$array ) or die 'options'; print "Scalar @$array\n"; GetOptions( 'an=s' => \@array ) or die 'options'; print "Array @array\n"; @array = (); GetOptions( 'aw=s@' => \@array ) or die 'options'; print "Array @array\n"; $ perl test-gol.pl --sn one --sn two --sw one --sw two --an one --an t +wo --aw one --aw two Scalar Scalar one two Array one two Array one two

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
