Hi gauravacl,

PID is "1425492", and now i want to find the exact file which is bigger in size and also it is opened by the process id. But when i tried your option i am getting the output as below,

myserv123>lsof -p 1425492
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
sas 1425492 ampsys cwd VDIR 46,42001 0 4043309312 /home/usr/SAS/IntTech (/dev/vx/dsk/)
sas 1425492 ampsys 0r VCHR 2,2 0t0 16628 /dev/null
sas 1425492 ampsys 1w FIFO 0xf1000100b2a35eb0 0
sas 1425492 ampsys 2w FIFO 0xf1000100b2a35eb0 0
sas 1425492 ampsys 3u IPv4 0xf10002000cabc398 0t0 TCP *:* (CLOSED)
sas 1425492 ampsys 5u unix 0xf10002000cbc7008 0t0 ->0xf10002000142c408
sas 1425492 rampsys 8u unix 0xf10002000ce2d808 0t0 ->0xf10002000d809008

I can see many lines, i want the file which growing faster or the bigger one, which belongs to the process id.

My Problem and target is:
Have to find the biggest file or fastly growing file in the file system and from that take the process id and the file name (with complete path). Then my action is to send a mail to corresponding user and have to kill the process by process id and have to remove the file (bigger or growing one which belongs to the process id).

kill.d

kill.d(1m)							   USER COMMANDS							kill.d(1m)

NAME

       kill.d - snoop process signals as they occur. Uses DTrace.

SYNOPSIS

       kill.d

DESCRIPTION

       kill.d is a simple DTrace program to print details of process signals as they are sent, such as the PID source and destination, signal num-
       ber and result.

       This program can be used to determine which process is sending signals to which other process.

       Since this uses DTrace, only users with root privileges can run this command.

EXAMPLES

       Default output, print process signals as they are sent.
	      # kill.d

FIELDS

       FROM   source PID

       COMMAND
	      source command name

       TO     destination PID

       SIG    destination signal ("9" for a kill -9)

       RESULT result of signal (-1 is for failure)

DOCUMENTATION

       See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
       bose descriptions explaining the output.

EXIT

       kill.d will run forever until Ctrl-C is hit.
