Getting at argv/argc is actually pretty simple in Perl. The global array @ARGV contains the arguments given on the command-line, but not the name of the file (this datum is contained in $0). Therefore your argv[1] in C is $ARGV[0] in Perl. The number of command-line arguments can be obtained in two ways, either you interpret the array in a scalar context and get its length: ``my $argc = scalar @ARGV'' or you use the last index of the array and add one: ``my $argc = $#ARGV + 1''. Of course, in most cases you'll just want to loop over the command-line args, so a foreach loop should suffice, or of course one of the Getopt (Getopt::Std or Getopt::Long in most cases) modules.
