Full Discussion: Closing open file descriptors from /proc/pid/fd
Top Forums Shell Programming and Scripting Closing open file descriptors from /proc/pid/fd Post 302559058 by ygemici on Monday 26th of September 2011 07:04:18 AM
Old 09-26-2011
Code:
process=your_process_name;for i in $(ps -ef|grep $process|grep -v grep|awk '{print $2}'); do 
echo -e "Printing Open Files by $process with $i PID\n$(lsof -p $i|awk 'NR>1')"
read -p "Dou you want to close $process with $i PID..[y/n]" c;if [ "$c" = "y" ] ; then kill $i;fi;done

if you close the process then open files was closed automatically by process if process has signal handlers,
if not , kernel executes default handler on process..

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.
