Re^2: Combining two scripts with a command line switch?

You guys are the best - that worked! Thanks!

One more quick question, how do I set it so that an argument is required? Right now I have:

my ($read,$generate,$help); # option switches
GetOptions (
    "help" => \$help,        
    "read"  => \$read,
    "generate" => \$generate,
);
[download]

If I run the it with any switch, it works perfectly - run it with no arguments, it does nothing at all. :) I'd like to add one more switch for a blank variable, so I can toss in a string that says "type -help for usage'."

Thanks very much as always!

I usually start scripts that require arguments with `die "Usage message\n" unless @ARGV;` [download] Make sure you put that before the call to GetOptions (it modifies @ARGV) "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply] [d/l]

how about: `my ($read,$generate,$help); # option switches GetOptions ( "help" => \$help, "read" => \$read, "generate" => \$generate, ); die "$Usage\n" unless $read \|\| $generate;` [download] Paul	[reply] [d/l]
