I have a data file that is nearly 14,000 lines long. It is a variable
length line. I have need to update this file twice a day with updated
information relative to the first field in this file. It is space
delimited and sorted on the first field. I need to replace the line
with information in an update log which has the same key (first field).
The update file could be as long as a hundred lines.
Is there a straight forward way of doing this?
I was going to do a merge and then sort and then uniq to remove the
duplicates but I was not able to assure that the update file entry was
the first line read in a uniq operation. My tests proved that I could
not control that the latest entry would be the first in the file.
