because the data in runtime.out is like this
Okay, suspected the second part, but you hadn't mentioned the format of runtime.out before so there was no way to know.

As I used comm with the -23 option, it wouldn't care about the old data of time.out at all, so that data would be safe, it would simply get the newest data from runtime.out, but the different file structure is a deal breaker unless you want to create a temporary file to hold data that can be comm'd to time.out.

I realize now that the reason you append a new line before inserting the data from runtime.out piped through tr to time.out is because after the last insertion, there is no newline since tr removes all newlines. I assume this is done on each and every record, so that you do wind up with newlines after each record, except for the last record.

I'd advisde changing this order if possible so the last record has a newline appended to it also, or that would be a deal breaker if you try to find a solution involving 'sed', because sed ignores lines w/o a newline at the end.

So if you make the line look as follows:
Code:
tr -d '\n' < runtime.out >> time.out;echo >> time.out

And then at the command prompt, one time only, before you run the collection script.

Code:
$> echo >> time.out

Then your good to go if you want to find a sed solution. That, however will take more time than I have today for me to look into it.

sendinpaths

SENDINPATHS(8)						    InterNetNews Documentation						    SENDINPATHS(8)

NAME

       sendinpaths - Send Usenet Path: statistics via e-mail

SYNOPSIS

       sendinpaths [-cdhn] [-k keep-days] [-r report-days] [address [address ...]]

DESCRIPTION

       sendinpaths checks pathlog/path for ninpaths dump files, finds dump files generated in the past report-days days, makes sure they are valid
       by running ninpaths on each one and making sure the exit status is zero, and passes them to ninpaths to generate a cumulative report.  By
       default, that report is mailed to the e-mail addresses configured at the beginning of this script (by default, only one address is
       configured: <top1000@anthologeek.net>) in order to supply the TOP1000 project with useful statistics.  See
       <http://top1000.anthologeek.net/> for more information.

       When finished, sendinpaths deletes all dump files in pathlog/path that are older than keep-days days.

       For more information on how to set up ninpaths, see ninpaths(8).

OPTIONS

       -c  When this flag is used, the report is also e-mailed, besides the default submission addresses or those given as command-line arguments,
	   to the newsmaster's address set at configure time.

       -d  Enables debug messages.

       -h  Gives usage information.

       -k keep-days
	   After having processed dump files, sendinpaths removes those that are older than keep-days days.  The default is 0, that is to say to
	   remove all dump files.

	   Setting keep-days to another value can be useful for debugging purpose because it permits to keep a few dump files.

       -n  Don't e-mail the report; instead, just print it to standard output.	Don't delete old dump files.

       -r report-days
	   Process dump files generated during the last report-days days.  The default is 32, that is to say to process all the dump files that
	   have been generated during the last 32 days (if, of course, they have not been deleted yet by a previous run of sendinpaths according
	   to the value set by the -k flag).

       address ...
	   E-mail the report to the mentioned address or addresses, instead of the default one.  Several addresses can be used, separated by
	   whitespace.	For instance, for two adresses:

	       sendinpaths pathsurvey@top1000.org top1000@anthologeek.net
