dbfdump
SHAPELIB(1) User Commands SHAPELIB(1)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 "Inte-
ger", "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.
EXIT STATUS
0 Successful program execution.
1 Missing file argument.
2 Failed to open file.
3 There are no fields in file.
DIAGNOSTICS
The following diagnostics may be issued on stdout:
DBFOpen(file,"r") failed.
There are no fields in this table!

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.
