in reply to Problem in passing multiple argument through command line

I prefer to use existing modules as shown by others. For simple options, however, I use the -s switch a lot.

$ cat clo.pl
#!/usr/bin/perl -s

use strict;
use warnings;
use vars qw($company $location);

$company ||= 'NO_COMPANY';
$location ||= 'NO_LOCATION';

printf "The %s company is located at $location\n",
       $company, $location;

$ ./clo.pl
The NO_COMPANY company is located at NO_LOCATION

$ ./clo.pl -company='Grant Alpho System'
The Grant Alpho System company is located at NO_LOCATION

$ ./clo.pl -company='Grant Alpho System' -location=TheOtherGlobe
The Grant Alpho System company is located at TheOtherGlobe

Or, if you only want to read a location with more customers, you can read from @ARGV yourself.

$ cat report.pl
#!/usr/bin/perl
use strict;
use warnings;

my($location, @customers) = @ARGV;
die "Can't create report, no customer defined\n" unless @customers;

print "The following customers are located at $location\n";
my $i;
for (@customers) {
  print ++$i, ". $_\n";
}

$ ./report.pl
Can't create report, no customer defined

$ ./report.pl NY Penelope Abraham Marie 'John Doe'
The following customers are located at NY
1. Penelope
2. Abraham
3. Marie
4. John Doe
