  27   27  The \fBkstat\fR utility examines the available kernel statistics, or kstats, on
  28   28  the system and reports those statistics which match the criteria specified on
  29   29  the command line. Each matching statistic is printed with its module, instance,

  56   56  matching kstats will be selected. A regular expression containing shell
  57   57  metacharacters must be protected from the shell by enclosing it with the
