combining files

1. list the files you want to concat

   ls | grep [pattern] > filelist

2. Review your files are in the proper order with vi or cat. If you use a suffix (1, 2, 3, ..., N) this should be no problem
3. Create the final file

   cat filelist | xargs cat >> [final file]

4. Remove the filelist

   rm -f filelist

Hope this helps anyone
