End of Month - Cron Jobs
I am running AIX 5.3 with the default shell as ksh.

I would like to know how to run a cron job on this system the last calendar day of the month. I found an example, but, I'm not sure if it will work with AIX and ksh...

Code:
02 16 * * * [ $(date +%d) -eq $(echo $(cal) | awk '{print $NF}') ] && /home/user/job-eom.ksh

I also need to be able to run a job on every day except the last calendar of the month (actually a series of jobs, but, I assume I can adopt the syntax for multiple jobs).

So to summarize:

I would like to run the following jobs where specified EXCEPT on the LAST calendar day of the month.

Code:
50   21   *   *   *   /home/user/eod-job1.ksh
00   22   *   *   *   /home/user/eod-job2.ksh
10   22   *   *   0   /home/user/eod-job3.ksh
10   22   *   *   1-4   /home/user/eod-job4.ksh
00   23   *   *   1   /home/user/eod-job5.ksh
10   22   *   *   5-6   /home/user/eod-job6.ksh
50   4    *   *   *   /home/user/eod-job7.ksh

And I would like to run another job ON the LAST calendar day of the month, and probably a couple of others...

Code:
45   20   *   *   *   /home/user/eom-job1.ksh

I'm also fairly new at shell scripting, etc., especially ksh.

NAME

       apticron - Generate a mail listing packages which are pending an upgrade

SYNOPSIS

       apticron [--cron]

DESCRIPTION

       apticron is a shell script which generates a mail with a list of all packages currently pending an upgrade, as well as summary of changes -
       using apt-listchanges - to a configurable Email address.

       apticron is mainly intended for automatic notification of pending security updates but can also be used	in  many  other  situations  where
       timely updates are necessary.

       The --cron option is only meant to be used when invoked by cron in order to run no more than once a day.

FILES

       /etc/apticron/apticron.conf
	      Configuration file, Email address to mail and profile for use with apt-listchanges are configurable.

       /etc/cron.d/apticron
	      Cron job for executing apticron daily.

       /etc/cron.daily/apticron
	      Fallback cron script for executing apticron (if no crond running or system down at designated time).

       /var/lib/misc/apticron.cron
	      Time stamp file used by apticron when invoked with --cron option.
