Removing trailer from a flat file!!!

Hi,

I get some flat files with trailer which gives the totol records count and i want to remove the trailer from the file.

i used the following command it works fine with a single file.

cat file_name | grep -v 'Total records:' > file1
mv file file_name

But i dont know how to remove the trailer when we have more than 1 file and how to redirect them and move them back to the original file name

The syntax of file is :

<date>.file_name.txt

something like 06222007.aaa_ddd_ccc_ddd.txt
06212007.aaa_ddd_ccc_ddd.txt
06202007.aaa_ddd_ccc_ddd.txt

Regards,
Kumar

gtkdoc-mktmpl(1)					      General Commands Manual						  gtkdoc-mktmpl(1)

NAME
gtkdoc-mktmpl -- GTK DocBook documentation generator. SYNOPSIS
gtkdoc-mktmpl [ See below ] DESCRIPTION
gtkdoc-mktmpl This creates or updates the template files which contain the manually-edited documentation. (A template is a simple text form which is filled in with the description of a function, macro, enum, or struct. For functions and macros it also contains fields for describing the parameters.) This script reads in the existing templates, found in tmpl/*.sgml, moves these files to tmpl/*.sgml.bak, and then recreates the .sgml files according to the structure given in the file MODULE-sections.txt. Any new templates added, or new function parameters, are marked with FIXME so you can do a grep to see which parts need updating. Any templates which are no longer used (i.e. they are remove from MODULE-sections.txt) are placed in the file tmpl/MODULE-unused.txt. If they are included again later they are automatically copied back into position. If you are certain that these templates will never be used again you can delete them from MODULE-unused.txt. Any parameters to functions which are no longer used are separated from the rest of the parameters with the line <!-- # Unused Parameters # -->. It may be that the parameter name has just been changed, in which case you can copy the description to the parameter with the new name. You can delete the unused parameter descriptions when no longer needed. EXAMPLE
See /usr/share/doc/gtk-doc-tools/examples, for a makefile.am and a configure.in example file. AUTHOR
