Shell Programming and Scripting

Hi All,

My target is to find the biggest files opened by any process and from that i have to find process id and the corresponding file also to avoid file system being hung-up.
Finding the process id: is to kill the process
Finding the biggest file: is to remove the file

To get the process id which is accessing the biggest file in the given file system, i am using the below command.

lsof -s /home/arun/my_work | awk '{print $7,$2}'| sort -n | tail -1 | awk '{print $2}'

Now i have to get the file name with complete path.
How can i achieve this? [with find command or whatever]
Please help.
