[Trisquel-users] Re : Need to compare numbers - Help with script

The script is also fast, which I was worried about given my files were very  
large.

Notice that the shell is slow.  It is a reason to substitute loops in shell  
scripts (like "while read line; do ... ; done < file") with calls to commands  
processing the whole input line by line.  Essentially all text-processing  
commands do that, AWK programs included.  If possible, those commands had  
better communicate through pipes, so that they run in parallel.
