A rude approach would be to use backticks:

my @proc = `ps -ax`;
my $cnt = $#proc;
print "Running processes: $cnt\n";

But while where already spawning a process, why not spawn 2 and save a line
of code:

my $cnt = `ps -ax | wc -l` + 0;
print "Running processes: $cnt\n";

For windows you can  use the Win32_Process of wmi , or for faster execution
use the Win::API module to call the psapi.dll

why not just

print `ps -ef | wc -l`;
