Error in Weekly.out log file

Question

I was just about to clone my MacintoshHD to a new SSD drive for my boot volume, so did a search for any basic cleanup tools or scripts or anything else I could do before creating the clone
I came across the fact that there are the daily weekly and monthly scripts that run by default within OS X.
On checking the logs I cam across this  and it has been happening every week since Sat Sep 12 12:51:09 BST 2009
Here it is:
Mon 14 Nov 2011 12:02:35 GMT
Rebuilding whatis database:
Running /etc/weekly.local:
-n Rotating psync log files:
/etc/weekly.local: line 17: syntax error near unexpected token `)'
/etc/weekly.local: line 17: `if [ -f /var/run/syslog.pid ]; then kill -HUP 0 101 80 79 102 103 81 98 106 104 0cat /var/run/syslog.pid | head -1); fi'
-- End of weekly output --
Is this an issue? obviously not a great one since I had not noticed it before..and as far as I know it has not created any issues to my use of the machine...just interested, that is all, and if I need to anything about it
Thanks

OK, thnaks for that.
I guess just deleting it is the answer, but if I do, will the in built scripts still run, just wondering where that script is called from when it runs, and did maybe the app that installed it, delete the entry that runs the in built scripts?
He is the offending script  and it loooks liek it came from a backup app called PsyncX
echo ""
echo -n "Rotating psync log files:"
cd /var/log
for i in psync.log; do
    if [ -f "" ]; then
        echo -n " "
        if [ -x /usr/bin/gzip ]; then gzext=".gz"; else gzext=""; fi
        if [ -f ".3" ]; then mv -f ".3" ".4"; fi
        if [ -f ".2" ]; then mv -f ".2" ".3"; fi
        if [ -f ".1" ]; then mv -f ".1" ".2"; fi
        if [ -f ".0" ]; then mv -f ".0" ".1"; fi
        if [ -f "" ]; then mv -f "" ".0" && if [ -x /usr/bin/gzip ]; then gzip -9 ".0"; fi; fi
        touch "" && chmod 640 "" && chown root:admin ""
    fi
done
if [ -f /var/run/syslog.pid ]; then kill -HUP 0 101 80 79 102 103 81 98 106 104 0cat /var/run/syslog.pid | head -1); fi
In my /private/etc/periodic/weekly folder there are two files
320.whatis
999.local
