extract string portion from filename using sed

Hi All,

I posted something similar before but I now have a another problem.

I have filenames as below

TOP_TABIN240_20090323.200903231830
TOP_TABIN235_1_20090323.200903231830

i need to extract the dates as in bold. Using bash v 3.xx

Im trying to using the print sed command but not getting the result I want

source_file_issue_date=`echo $fname | sed '/_[0-9][0-9]*[.]/p'`
echo "source_file_issue_date: $source_file_issue_date"


Appreciate any ideas?!

Kind Regards
Satnam

AMARCHIVER(8)						  System Administration Commands					     AMARCHIVER(8)

NAME
amarchiver - Create, extract or list amanda archive SYNOPSIS
amarchiver --version|--create|--extract|--list [--verbose] [--file file] [filename]... DESCRIPTION
Amarchiver manipulates amanda archive file. On creation, amarchiver doesn't recurse into directories. If a filename specifies a directory, it will be ignored. If it specifies a character device, amarchiver reads the device and archives the data. If a filename specifies a named pipe, amarchiver reads the named pipe and archives the data. Note that this tool is more limited than the Amanda archive library, and may not be appropriate for some archive files -- particularly those which use non-strings in their filenames. OPTIONS
--version print the amarchiver version --create Create an amanda archive. Only the supplied filenames are included. With one --verbose, lists the filenames. With two, lists the filenames and sizes. --list List the filenames in an amanda archive. No additional filenames are allowed on the command line. --extract Extract an amanda archive. If filenames are supplied, only those files are extracted. Files are created in the current directory, suffixed with a dot ('.') and the attribute ID. --verbose Give more information. --file file Create, list or extract from the given file instead of stdin/stdout.
