Full Discussion: crontab entry to run every last day of the month
Top Forums Shell Programming and Scripting crontab entry to run every last day of the month Post 302133846 by jbuberel on Sunday 26th of August 2007 08:54:53 PM

My simple solution...
Was to turn the date math trick shown above into a script that I named 'last-day-of-month.sh':
Code:
#!/bin/bash

TODAY=`/bin/date +%d`
TOMORROW=`/bin/date +%d -d "1 day"`

# See if tomorrow's day is less than today's
if [ $TOMORROW -lt $TODAY ]; then
        exit 0
fi

exit 1

Which can then be used within a crontab file as follows:
Code:
12 0 * * * last-day-of-month.sh && /run/my/cron/job.sh

I hope this is of some use to you...

nnstats

NNSTATS(1m)															       NNSTATS(1m)

NAME

       nnstats - display nnmaster collection and expire statistics

SYNOPSIS

       nnstats [ -lt ] [ -d month day ] [ -m month ] [ logfile ]...

DESCRIPTION

       nnstats	will  extract  the collection (C) and expiration (X) entries from the log file and calculate total and average number of articles,
       groups and elapsed time per day, per month, or for the duration of the whole log file.

       Normally only a summary for the specified period is printed.  If -l is specified, the statistics  for  each  day  in  the  period  is  also
       printed, and if -t is specified the summary is not printed.

       Normally the statistics is collected for all days in the log files (or the current log file if one is not specified).

       If  "-m	month" is specified, the statistics for that month is calculated.  The month is specified in normal date notation, i.e. a capital-
       ized three letter abbreviation like Jan, Feb, ...

       If "-d month day" is specified, the statistics for that date only is calculated and printed.

FILES

       ../Log	The log file

SEE ALSO

       nn(1), nnusage(1M), nnadmin(1M), nnmaster(8)

NOTES

       If nnmaster is run with options -LCX, nnstats will not work, because the necessary entries are not written to the log file.
