Shell script to report file size, pid and also kill the process

Hi All, Looking for a quick LINUX shell script which can continuously monitors the flle size, report the process which is creating a file greater than certain limit and also kill that process. Can someone please help me on this?

Thanks for the response. I am new to UNIX scripting. I am trying to put all the commands together and write a script.

Code:
#!/bin/sh
find /data  -type f -size +1G > $file
ps -ef | grep $file | awk '{print $2}' > $PID
 kill -9 $PID

Your specification is - even more than - a bit vague. Please indicate how frequently the file size should be checked. By using a loop / crontab entry? Report to whom / how? Are you sure the identified process may be killed?

Thank You for your reply. The script should be executed every few minutes and I can schedule it in crontab. It should report the PID, source of the file and also the job should be killed and the file should be deleted.

so i tried and was able to get here. Any feedback or changes

Code:
#!/bin/sh
filename='bigfiles'
find /opt/karthik -type f -size +200M > $filename
count='cat bigfiles | wc -l'

#while read LINE; do echo "$LINE" |

while read -r line;do [ -n"$line" ] &&

pid= ps -ef | grep -v grep |  grep $(basename "$line") | awk '{print $2}' >> pid.txt
kill $(ps -ef | grep -v grep | grep $(basename "$line") | awk '{print $2}'); rm -- $line
done < $filename

------ Post updated at 05:42 PM ------

Instead of ps i want to replace with something which can find the process ID of the process creating the file. Any idea?
