You can do
Code:
LOG=/var/ovd/ConfigLogs
m=5
for n in 4 3 2 1
do
  [ -f $LOG.$n.bz2 ] && mv $LOG.$n.bz2 $LOG.$m.bz2
  m=$n
done
cp -p $LOG $LOG.1
> $LOG
bzip2 $LOG.1

A crontab entry logs like this
Code:
00 10 * * 5 /path/to/rotatescript

and can be created with e.g.
Code:
EDITOR=vi crontab -e

--
If you have root rights I would go for logadm. It is only one command
Code:
logadm -w /var/ovd/ConfigLogs -c -C 5 -p 1w -z 0 -P 'Sat Nov 02 10:00:00 2013'

and an entry is added to /etc/logadm.conf.
No crontab entry is needed, because the existing logadm entry handles all the /etc/logadm.conf.

logadm.conf

logadm.conf(4)							   File Formats 						    logadm.conf(4)

NAME

       logadm.conf - configuration file for logadm command

SYNOPSIS

       /etc/logadm.conf

DESCRIPTION

       /etc/logadm.conf  is  the default configuration file for the log management tool logadm(1M). Comments are allowed using the pound character
       (#) and extend to the end of line. Each non-comment line has the form:

       logname options

       where logname is the name of the entry and options are the default command line options for the logadm command. The name of the	entry  may
       be  the	same  as  the  name of the log file, or a log file name may be given in the options section of the entry. Long lines may be folded
       using a backslash followed by a newline to continue an entry on the next line. Single or double quotes may be used  to  protect	spaces	or
       alternate-style quotes in strings.

       The  preferred  method  for  changing  /etc/logadm.conf	is to use the -V, -w, and -r options to the logadm(1M) command, which allow you to
       lookup an entry, write an entry, or remove an entry from /etc/logadm.conf.

       A full description of how and when /etc/logadm.conf is used and sample entries are found in logadm(1M).
