NAME
dbfdump - dump xBase DBF files as text
SYNOPSIS
dbfdump [-h] [-m] [-r] file
DESCRIPTION
Dumps the contents of file to standard output. The first line contains
the field names appearing in file, and each of the following lines contains the field values of a record. Field names and values are padded
by spaces to their field widths. Empty fields are printed as the
string "(NULL)".
OPTIONS
- -h Prints the column field definitions before other output. Each
- field definition consists of a line of the form
- Field: index, Type=type, Title=`name', Width=width, Decimals=precision
- where index is the zero offset column number of the field; the type indicates the datatype of the field value and is either "Integer", "Real" or "String"; name is the field's name; width is the number of bytes reserved for the field's value; and precision is the number of decimal places of precision for "Real" type fields, and is zero for "Integer" and "String" type fields.
- -m Prints each record in multiline format separated by empty lines.
- The first line of a record gives the number of the record in the form
- Records: record_index
- where record_index is the zero offset number of the record in the file, and then each field of the record appears on its own line in the format
- name: value
- -r Prints the exact bytes occurring in file for field values and
- suppresses printing "(NULL)" for empty values.

BUGS
Unless the -r option is given, values in numeric fields that overflow
the int or double types of the C language are printed as plus or minus
a huge number. For integer fields the huge value is HUGE_VALL from
<stdlib.h> and for real fields it is HUGE_VALF.
