NAME
     validata - validate columnar file for consistency

SYNOPSIS
     validata

DESCRIPTION
     _V_a_l_i_d_a_t_a reads a file from the standard input and for each
     column in its input, reports statistics about the type of
     field.  By type of field, I mean whether a column contains
     alphanumeric strings, integers, real numbers, or something
     else.  _V_a_l_i_d_a_t_a also tells the maximum and minimum values of
     the columns; _V_a_l_i_d_a_t_a is useful to check data files for con-
     sistency before input to some data analysis program as it
     can detect missing columns or columns of the wrong type,
     such as non-numeric input.

SEE ALSO
     unixstat(1), maketrix(1)

     sort(1), grep(1), uniq(1) are also useful for checking data
