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 Page 1 Frequencies for the values in columns 210-210 in the file "data.file" Value Cumulative Cumulative Value Frequency Percent Frequency Percent ------- --------- ------- ---------- ---------- 0 2214 11.37 2214 11.37 1 1009 5.18 3223 16.55 2 533 2.74 3756 19.28 9 15721 80.72 19477 100.00
