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.
