Question Merging files belonging to same date in a directory

Hi,

I want to merge files which belong to the same date in a directory.
For ex:

The below two files are modified on 24 Apr 2007.

SystemOut.log
SystemOut_07.04.24_19.46.40.log

The merged file should be of the format SystemOut.log.2007.04.24

VK_LOGMERGE(1)						      General Commands Manual						    VK_LOGMERGE(1)

NAME
vk_logmerge - a Valgrind XML log file merger SYNOPSIS
vk_logmerge [flags and input files in any order] DESCRIPTION
vk_logmerge is a valkyrie(1) helper. Given multiple log files (in xml format) generated by multiple runs on a parallel machine, or multiple log files generated by sequential runs on a single-processor machine, for the same binary, vk_logmerge merges the log files together, sum- ming the counts of duplicates, and outputs the result to a single file. As input, vk_logmerge expects the log-files to-be-merged and/or a file containing the list of log-files to-be-merged, with each entry on a separate line. Log files can be merged from within valkyrie(1) , or use can invoke vk_logmerge directly. OPTIONS
-h Show help message -v Be verbose (more -v's give more) -t Output plain text (non-xml) -f <log_list> Obtain input files from <log_list> file (one per line) -o <writefile> File to write output to At least 1 input file must be given. If no '-o outfile' is given, writes to standard output. EXAMPLES
vk_logmerge log1.xml -f loglist.fls -o merged.xml SEE ALSO
