Mastering Unix : AWK Commands

      Pgawk is the profiling version of gawk.  It is identical in  every  way

       to  gawk,  except  that  programs run more slowly, and it automatically
       produces an execution profile in the file awkprof.out when  done.   See
       the –profile option, below.

       The  command  line  consists of options to gawk itself, the AWK program
       text (if not supplied via the -f or –file options), and values  to  be
       made available in the ARGC and ARGV pre-defined AWK variables.
