The command line is: freq2.pl [-h] [-c[#-#][#] [-n] filename] where: -c#-# indicates starting & ending column numbers of the variable, -c# indicates a single-column variable at column #, and -n selects a numeric sort of the output instead of the default character sort.
As an example, the command freq2.pl -c210 data.file might produce output like:
(pts/1):~> freq2.pl -c210 data.file
