In an oct-file why not something like

std::ostringstream buf;
buf << "zenity --progress --title=\"Update System Logs\"
--text=\"Scanning mail logs...\" --percentage=0"
oprocstream filter (buf.str ());
if (filter && filter.is_open ())
  {
    filter << "echo \"10\"; sleep 1\n";
    filter << "echo \"# Updating mail logs\" ; sleep 1\n";
    filter << "echo \"20\" ; sleep 1\n";
    filter << "echo \"# Resetting cron jobs\" ; sleep 1\n";
    filter << "echo \"50\" ; sleep 1\n";
    filter << "echo \"This line will just be ignored\" ; sleep 1\n";
    filter << "echo \"75\" ; sleep 1\n";
    filter << "echo \"# Rebooting system\" ; sleep 1\n";
    filter << "echo \"100\" ; sleep 1\n";
    int status = filter.close ();
    if (!WIFEXITED (status) || WEXITSTATUS (status) != 0)
      warning("zenity filter exited abnormally");
  }
