[osmosis-dev] Merge huge count of files

Hi,

You don't say what kind of files you are merging but it is possible that 
the best strategy is not using Osmosis at all for this task.

If you have plain simple OSM XML files then the following will merge 
them super fast:

(echo '<osm version="0.6">'; cat *osm|grep -v "<osm"|grep -v 
"</osm"|grep -v "<?xml"; echo '</osm>') > newfile.osm

You can add an Osmosis sort step if you want.

Bye
Frederik
