Re: getopt::std help

Add this to see what's going on:

use Data::Dumper;
print Dumper $o;
[download]

And you'll see that the key 'h' _is_ being created, and the value is undef, which is why your if statements don't pick it up, since it's a false value. This will do what you want:

usage() if exists $o->{h};

doh.. Thank you. One more thing, will using getopt automatically reject the flags that are not explicitly specified (getopt('hltf', $o);), meaning if I call a program w/ ./program -x , Will getopt automatically reject and abort the program or do I need to tell the program that?	[reply]

Try running `./program -x` and see what happens. Sometimes the best way to learn is to experiment;)	[reply] [d/l]

just to follow up on my post and also just in case there are newbies on this site like me who is having trouble deciphering other official document on getopt::Long, I ran into below page which gave me enough examples and definition for my slow head to understand bit better.. just wanted to share But I thank all the experts who reply to my posts as always :-) as there is nothing like coming here and get help/advice/encouragement(sometimes kick in the ass) to continue my journey of perl.. I love perl!!!! http://world.std.com/~swmcd/steven/perl/pm/getopt.html	[reply]
