If you want to capture the output of your program then you could use either backticks or open(). If however you just want to execute the program and are not concerned about the output then system() would be your best option e.g

## backticks
my $output = `your_program`;

## alternate backtick syntax
my $output = qx(your_program);

## open
open(my $prog, "your_program|") or die("ack - $!");
my $output = join '', <$prog>;

## system
system("your_program") == 0 or  die("program exitted abnormally");
