Find Which Process Binded to my Port:

                                                                                                                                                  

There are lot of instances whereWe will come across a situation where we need to chase to find the process

for a give port , if there are 20-30 of java process running  on box.

Developers are no clue whatz going , what process they are killing what process they are starting etc etc

Here is a sample script which will take port as input and give us the process id

#!/bin/bash

if [ $# -lt 1 ]
then
echo "Usage: getpid.sh |port| "
echo "Please retry with correct options"
echo "if you want to suppress the output with unnecessary string like 'permission denied'"
echo "Use: ./getpid.sh |port| > 2>/dev/null "
exit
fi

echo "Scanning for your port............!!!!!!!!!!!!!!"

ls /proc | while read i
do
pfiles $i | grep AF_INET | grep $1 |grep peername
if [ $? -eq 0 ]
then
echo Is owned by pid $i
echo
fi
done
echo "Script Completed Successfully..."
echo 

./getSolarisPid.sh 12082 

./getSolarisPid.sh 12082 2>/dev/null (if you want to supress the permission denied messgs')

 LINUX
