I get different command-line parm results using the functions getopt() vs getopts(). The doc I have read only mentions that getopts() will warn the user on unknown switches.

In the sample code below, the output will change depending on wheather you're using getopt() or getopts(). 

use strict;
use Getopt::Std;

our ($opt_h, $opt_a);
getopt('ha');
print "help=$opt_h\n" if (defined $opt_h);
print "all=$opt_a\n"  if (defined $opt_a);

Results with getopt

perl -w test.pl -h -a
help=-a

Results with getopts

perl -w test.pl -h -a
help=1
all=1

[download]

So, at this point I know how to get what I want (use getopts). However, being a perl newbie and in learn mode, I am curious about this behavior.

Could this be a platform issue?
