# 8  
Old 12-19-2016
With this sort of thing I like to just get epoch times for the dates I'm working with and then use simple integer math to navigate like this:

Code:
#!/bin/ksh

TEMP=/file/home/test.txt
trap "rm -f $TEMP" SIGHUP SIGINT EXIT

day=$(printf "%(%s)T" "last month")
to=$(printf "%(%s)T" "this month")

while [ $day -lt $to ]
do
   w=$(printf "%(%Y-%m-%d)T\n" \#$day)
   XXX=$(grep $w /honey/logs/statistics/s* | wc -l )
   echo "S" $w " :"$XXX >> $TEMP
   let day=day+60*60*24
done

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
