My problem: Using getopt::Long , using options with both arguments and no arguments

example1: ./ldapadmin --adduser
example2: ./ldapadmin --adduser Manuel,Castillo,F

(basically I want the program to know 'adduser flag is on with no arguments' or 'adduser flag called with arguments')

Both of these should work. Reading the Getopt::Long documentation, I noticed that you can set arguments as optional via : character instead of = (ex. 'adduser:s' => \@adduser) however, in example 1, the value of @adduser is false as if it has never been called!

my possible workaround: use $#ARGV and @ARGV before calling getoptions and keep track of flag this way, if $ARGV[0] contains --adduser and value of $#ARGV is 1, then it mustve been called with no arguments.

problem: Am i using getoptions incorrectly? Module documentation doesn't seem to be too informative, too short if you ask me.

here is a piece of my code---------------------------

my $argn = $#ARGV;   #  num of args stored in $argn
my @argvee = @ARGV;  #  actual arguments stored in @argvee

# above was done before GetOptions loads, since it seems to eat ARGV..

GetOptions (
    'adduser:s' => \@adduser,
    'deluser=s' => \$deluser,
    'addgroup=s' => \@addgroup,
    'delgroup=s' => \$delgroup,
    'addu2g=s' => \@addu2g,
    'delu2g=s' => \@delu2g,
    'chsh=s' => \@chsh,
    'addalias=s' => \@addalias,
    'delalias=s' => \@delalias,
    'list' => \$list,
    'help' => \$help );

@adduser = split(/,/,join(',',@adduser)); #take in info and split on c
