  I'm not sure what you want exactly, could you please elaborate?
  If what you need is to combine the contents of several log directories
into one single file, it's easy:

  - make sure your log files are all timestamped with the same format
(i.e. all TAI64N or all ISO 8601).
  - concatenate them all and sort the result.
  The resulting file will be a log file sorted chronologically.

for logdir in `cat logdir_list` ; do (cd $logdir && cat *.s *.u current) ; done | sort > logfile

  It's generally much easier to gather than to scatter, which is why the
logging chain model is superior to the syslogd model.
