Re: Help required on Getopt::Long

Problem Solved!

Just replace '=' with ':' at line 5

Here is the code.

use Getopt::Long;
my $abc;
my $help;
 
GetOptions ( "abc:s" => \$abc,
                   "help" => \$help
                 );
 
if ($help) { print "This is help message\n" ; exit ;}
 
if ($abc) { print "You have choosen \"abc\" as $abc" };

Replacing equal sign with colon alone does not solve the problem. It changes the problem by making the value for option `abc` optional instead of being required; equals sign impose that a value need to be specified ... `= type [ desttype ] [ repeat ] The option requires an argument of the given type. . . . : type [ desttype ] Like "=", but designates the argument as optional. If omitted, an empty string will be assigned to string values options, and the value zero to numeric options.` [download]	[reply] [d/l] [select]

".. equals sign impose that a value need to be specified ..." -- self. GAAH! Make that "... equals sign imposes that a value is need to be specified ...".	[reply]
