NAME
validata - validate columnar file for consistency
SYNOPSIS
validata
DESCRIPTION
_▶08◀V_▶08◀a_▶08◀l_▶08◀i_▶08◀d_▶08◀a_▶08◀t_▶08◀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. _▶08◀V_▶08◀a_▶08◀l_▶08◀i_▶08◀d_▶08◀a_▶08◀t_▶08◀a also tells the maximum and minimum values of
the columns; _▶08◀V_▶08◀a_▶08◀l_▶08◀i_▶08◀d_▶08◀a_▶08◀t_▶08◀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
