   I've solved this part now as well.  The following command does it   
   (originally all one line):   
      
   find 'Family History/_all' -name "*.png" | sort | sed -E '{ h;   
   s~/_all/[1-5][ont]{1,2}~~ ; s~ +\([ont]{1,2}\)~~ ; G ; s/\n/\t/ }' |   
   sort | sed 's/^[^\t]\+\t//' > 'Family History/_all/FHBlinkList.txt'   
      
   The most complex part is the first sed command, so I will explain it:   
      
   h	Copy input, the original full pathname, to the hold space   
   s 2x	Remove the '/_all/*' and ' (*)' parts of the pathname   
   G	Retrieve and append the original line from the hold space   
   s	Replace the intervening new line character with a tab   
      
   The second sed command removes the first part of the line up to and   
   including the tab which was used as a key in the final sort immediately   
   previously.   
      
   However, although the problems as originally stated are now both solved,   
   I need to do this second stage better, as I need to exclude from the   
   list those files that already have a chosen final copy in the main part   
   of the archive.
