I know I can get this information from a system
call to "ps", but is there a way to tell if a
program in running from Raku?

Running ps is probably as good as anything, but in linux you could
always just poke around under /proc,
e.g. Loop over /proc/*/cmdline and look for it.

Follow up:

   $PsStr = qqx ( ps ax );
   if $PsStr.contains( "gnucash" )  {
      PrintGreen( "GnuCash is running\n\n" );
   } else {
      # qqx ( gnucash );
      my $pA = Proc::Async.new( "/usr/bin/gnucash" );
      $pA.start;
      PrintGreen( "GnuCash started\n\n" );
   }
