If I understand you correctly, you have a list of files in /tmp/orders, 
and you want to count the total lines in those files.

If so, it seems like you could do it like this:

# wc -l $(cat /tmp/orders) | tail -1

This assumes the filenames in /tmp/orders are full paths, or in the 
current directory.  You're just running 'wc' on all of the files, and 
when you do that it prints a final line with the total it counted.  
Using 'tail' keeps just that line.

HTH,
Jeff
