Getopt::Long Help with Mandatory String Opt

amt has asked for the wisdom of the Perl Monks concerning the following question:

It's been a long time since I've got my hands dirty with Perl, so forgive me if this question seems elementary. I am hitting the second if() from this code block when running the below line from the command prompt. Any help would be much appreciated.

my ($db,$killswitch,$configDepth,$hostname)  #default values
=  (0  ,0          ,-1          ,''); 
GetOptions(    'v!' => \$db
    ,    'k!' => \$killswitch
    ,    'd=i'=> \$configDepth
    ,    'H=s'=> \$hostname
    );

if( $configDepth == -1){ print $0.' requires the -d switch with a dept
+h value.'.$cr; die; }
if( $hostname == ''   ){ print $0.' requires the -H with a hostname or
+ comma-seperated list of hostnames.'.$cr; die;}

And here is the line:

 $>traverse.pl -v -H WSTM0165815 -d=1
C:\depot\code\util\pl\traverse.pl requires the -H with a hostname or c
+omma-seperated list of hostnames.
Died at C:\depot\code\util\pl\traverse.pl line 34.

Use warnings! You're checking for numerical equivalence (`==`) instead of string equivalence (`eq`).	[reply] [d/l] [select]

It is apparent that my script-fu has become very weak. Have an upvote. amt. perlcheat	[reply]
