OK, between the suggestions you and Mark put forth, I think I'm on to
So far I've got a program that will read each file in turn, generating a
time stamp (DOY, for Day Of Year) for each line of data based on month,
day, hour, minute on the fly. The DOY is used for a key to an element of a
hash which is the line of data.
So, now I've got one hash for each file, and I ~think~ I know how to get an
array of keys...
Next trick is to merge the arrays of keys, eliminate duplicates, and sort
into numerical/chronological order. Then I can write a line consisting of
the key (the DOY) and the lines of data from each file that match that key,
or blank spaces if there is no data in one or more of the files.
The part I need to learn now is how to do the cat |sort...back to Mr.
