Delete filename with month -2
KSH - I've got a script that is generating a number of log files like this:

y=`date +"%y"`
m=`date +"%m"`

$LOG_DIR/tuscprof_tbl_$y$m.log

I only want to keep the current 2 months' worth of files (current month and prior month). So I'm trying to come up with a way to delete any that contains a filename month that is -2 from current month.

I thought I could do it like this, but it's not working:

if [[ -e $LOG_DIR/*_$(($y))*.log && -e $LOG_DIR/*_*$(($m - 2)).log ]]
then rm $LOG_DIR/*_*$(($m - 2)).log
fi

if [[ -e $LOG_DIR/*_$(($y - 1))%*.log && ! $m -eq 01 ]]
then rm $LOG_DIR/*_$(($y - 1))%*.log
fi

NAME

       ds.log - Availability Suite data services log file

DESCRIPTION

       The  /var/adm/ds.log file contains the Availability Suite data services command log. The administration commands log activities to the file
       in the format:

	 date time product: message

       Note that when the size of the log file exceeds 10 Mbytes, ds.log is renamed  /var/adm/ds.log.bak  and a new /var/adm/ds.log file  is  cre-
       ated.

       The ds.log fields are:

       date

	   The	date format is mmm nn, where mmm  is  the local three-character abbreviation for the month and nn is the day of the month on which
	   the event occurred.

       time

	   The time of the event, in hh:mm:ss format.

       product

	   A product code that identifies which component of the data services produced the event. The code is separated  from	the  message  that
	   follows by a colon (:) and a space.

       message

	   A  message  that  can extend over  more  than  one  line describing the event that occurred. The second or following lines are not pre-
	   fixed by  the  date, time, and product code strings.

EXAMPLES

       The example below shows sample ds.log file content:

	 Jan 25 05:26:17 ii: iiboot suspend cluster tag <none>
	 Jan 25 05:32:02 ii: iiboot resume cluster tag <none>
	 Jan 25 05:32:04 sv: svboot: resume /dev/vx/rdsk/bigmaster
