Splitting a file and sending results to another file
Hi

Here is my script:

Code:
 
#!/bin/bash
set -x
dir="/var/local/dsx/import"
gawk -F, '
 $1 == last1 && $2 == last2 {
  printf $0"\n" >> $dir/$2
 }
 $1 !=last1 || $2 != last2 {
  printf $0"\n" >> $dir/$2
 }
 {
  last1=$1
  last2=$2 
 } 
 '  $1

Here is my test file:

Code:
 
o,e,r
1,2,3
1,2,3
1,2,3
4,5,6
4,5,6
4,5,6
4,5,6
4,5,6
4,5,6

Basically I want to split my file and send the haf to another file, but I get this error:
Code:
gawk: cmd. line:5: (FILENAME=t FNR=1) fatal: division by zero attempted

Can somebody please help

Detailed Description
   template<typename _CharT>class std::numpunct< _CharT >
       Primary class template numpunct.

       This facet stores several pieces of information related to printing and scanning numbers, such as the decimal point character. It takes a
       template parameter specifying the char type. The numpunct facet is used by streams for many I/O operations involving numbers.

       The numpunct template uses protected virtual functions to provide the actual results. The public accessors forward the call to the virtual
       functions. These virtual functions are hooks for developers to implement the behavior they require from a numpunct facet.

Member Function Documentation
   template<typename _CharT > char_type std::numpunct< _CharT >::decimal_point () const [inline]
       Return decimal point character. This function returns a char_type to use as a decimal point. It does so by returning returning
       numpunct<char_type>::do_decimal_point().

       Returns:
	   char_type representing a decimal point.

   template<typename _CharT > virtual char_type std::numpunct< _CharT >::do_decimal_point () const [inline],  [protected],  [virtual]
       Return decimal point character. Returns a char_type to use as a decimal point. This function is a hook for derived classes to change the
       value returned.

       Returns:
	   char_type representing a decimal point.

   template<typename _CharT > virtual string_type std::numpunct< _CharT >::do_falsename () const [inline],  [protected],  [virtual]
       Return string representation of bool false. Returns a string_type containing the text representation for false bool variables. This
       function is a hook for derived classes to change the value returned.

       Returns:
	   string_type representing printed form of false.

       Definition at line 1845 of file locale_facets.h.

   template<typename _CharT > virtual string std::numpunct< _CharT >::do_grouping () const [inline],  [protected],  [virtual]

       derived classes to change the value returned.

       See Also:
	   grouping() for details.

       Returns:
	   String representing grouping specification.

       change the value returned.

       Returns:
	   char_type representing a thousands separator.

       Definition at line 1806 of file locale_facets.h.

   template<typename _CharT > virtual string_type std::numpunct< _CharT >::do_truename () const [inline],  [protected],  [virtual]

       is a hook for derived classes to change the value returned.

       Returns:
	   string_type representing printed form of true.

   template<typename _CharT > string_type std::numpunct< _CharT >::falsename () const [inline]
       Return string representation of bool false. This function returns a string_type containing the text representation for false bool
       variables. It does so by calling numpunct<char_type>::do_falsename().

       Returns:
	   string_type representing printed form of false.

       Definition at line 1777 of file locale_facets.h.

   template<typename _CharT > string std::numpunct< _CharT >::grouping () const [inline]
       Return grouping specification. This function returns a string representing groupings for the integer part of a number. Groupings indicate
       where thousands separators should be inserted in the integer part of a number.

       Each char in the return string is interpret as an integer rather than a character. These numbers represent the number of digits in a group.
       The first char in the string represents the number of digits in the least significant group. If a char is negative, it indicates an
       unlimited number of digits for the group. If more chars from the string are required to group a number, the last char is used repeatedly.

       For example, if the grouping() returns '0302' and is applied to the number 123456789, this corresponds to 12,34,56,789. Note that if
       the string was '32', this would put more than 50 digits into the least significant group if the character set is ASCII.

       The string is returned by calling numpunct<char_type>::do_grouping().

       Returns:
	   string representing grouping specification.

       Definition at line 1751 of file locale_facets.h.

   template<typename _CharT > char_type std::numpunct< _CharT >::thousands_sep () const [inline]

       numpunct<char_type>::do_thousands_sep().

       Returns:
	   char_type representing a thousands separator.
