Re: Re: Making Getopt::Long tell me if no parameters passed

Thanks.

I decided to go with

&usage if not defined $user;
&usage if not defined $pass;
&usage if not defined $config;
[download]

until I could figure out something more elegant.

Cheers,

$ echo '$0 & $0 &' > foo; chmod a+x foo; foo;

fever pointed out the right thing to do, but just for completeness' sake, your approach could be condensed, too. The obvious, naive version: `&usage unless (defined $user) or (defined $pass) or (defined $config);` And the Once And Only Once version: `&usage unless grep defined, $user, $pass, $config;` That said, go with passing `GetOptions` a hashref. Makeshifts last the longest.	[reply] [d/l] [select]
