Bug Splitting a string and putting another string in the middle?
Hello all!

I'm trying to put together a small script that will take in a file name and attach a datestamp to the end of it (but before the file type extension).

To illustrate...

Before:
filename.txt
anotherfilename.txt

After:
filename_20090724.txt
anotherfilename_20090724.txt

Searching around the forums I've found some pieces that I think are parts of the solution:

Code:
 
date +%Y%m%d ---->gets me my datestamp format
expr index string . ------>gets me the character position of '.'

So now my question is how to substring the file name from the beginning to the period and also substring from the period to the end...giving me my two halves of the full name so that I can concatenate my datestamp in between. Any help is very appreciated.

Thanks!
Glen

gtkdoc-mktmpl

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.
