HP Remove Last field from a delimited file
Hi,

I have a '~' delimited file and i want to remove the last field using awk. Please find the sample records below:

Code:
1428128~1~0~1100426~003~50220~005~14~0~194801~11~0~3~14~0~50419052335~0~0820652001~2~00653862 ~0~1~0~00126~1~20000110~20110423~R~          ~0~Z~1662.94~ ~002041~0045~Z~
1428128~1~0~1100426~003~50220~005~14~0~194801~11~0~3~14~0~50419052335~0~0820652001~2~00653862 ~0~1~0~00126~1~20000110~20110521~R~          ~0~Z~3039.46~ ~002041~0045~Z~
1428128~1~0~1100426~003~50220~005~14~0~194801~11~0~3~30~0~50419052335~0~0820652001~2~00653862 ~0~1~0~00126~1~20000110~20110623~R~          ~0~Z~3039.46~ ~002041~0045~Z~

And also after removing the last field i want the last '~' associated with the last field to be removed for each line.

Any help appreciated...

Thanks,

Arun

PERLDELTA(1)						 Perl Programmers Reference Guide					      PERLDELTA(1)

NAME

       perldelta - what is new for perl v5.8.1

DESCRIPTION

       This document describes differences between the 5.8.0 release and the 5.8.1 release.

Incompatible Changes
Core Enhancements
       Tied Arrays with Negative Array Indices

       Formerly, the indices passed to "FETCH", "STORE", "EXISTS", and "DELETE" methods in tied array class were always non-negative.  If the
       actual argument was negative, Perl would call FETCHSIZE implicitly and add the result to the index before passing the result to the tied
       array method.  This behavior is now optional.  If the tied array class contains a package variable named $NEGATIVE_INDICES which is set to
       a true value, negative values will be passed to "FETCH", "STORE", "EXISTS", and "DELETE" unchanged.

       Warnings

       Perl 5.8.0 forgot to add some deprecation warnings.  These warnings have now been added.

       Pseudo-hashes really are deprecated

       Pseudo-hashes were deprecated in Perl 5.8.0 and will be removed in Perl 5.10.0, see perl58delta for details.  Each attempt to access
       pseudo-hashes will trigger the warning "Pseudo-hashes are deprecated".  If you really want to continue using pseudo-hashes but not to see
       the deprecation warnings, add:

	   no warnings 'deprecated';

       5.005-style threads really are deprecated

       5.005-style threads (activated by "use Thread;") were deprecated in Perl 5.8.0 and will be removed in Perl 5.10.0, see perl58delta for
       details.  Each attempt to create a 5.005-style thread will trigger the warning "5.005 threads are deprecated".  If you really want to con-
       tinue using 5.005 threads but not to see the deprecation warnings, add:

	   no warnings 'deprecated';

       If you find what you think is a bug, you might check the articles recently posted to the comp.lang.perl.misc newsgroup and the perl bug

       If you believe you have an unreported bug, please run the perlbug program included with your release.  Be sure to trim your bug down to a
       tiny but sufficient test case.  Your bug report, along with the output of "perl -V", will be sent off to perlbug@perl.org to be analysed by
       the Perl porting team.
