Before running out to buy Microsoft Word (or another industrial-strength and expensive) word processing program for your Mac, remember that Apple includes a respectable word processor with OS X. The program is TextEdit, and it call s the Applications folder home. I've tried and used all available outliners for Mac OS X, but Process is the one which appears to be more Mac-like than any other app. After using OmniOutliner for quite a long time, I've switched.
To find the process that is listening to a port on Mac OS X, we’ll use the lsof command to find the process ID (PID), and the ps command to show the name.

Find the Process ID (PID)
There are two different ways we can use to find the process that is listening to a port on Mac OS X.
Find the Process ID (PID) Using lsof
Using the lsof command we can find the process ID (PID) for a specific port that is in a LISTEN state. In a terminal type the following and replace the “<port-number>” with our port number.
This generates output that looks like this:
In the output above the PID (process ID) is the second value, in this example output the process ID (PID) is “63851”. This command will also print out the port number, which is 9999 in the above output example.
Find the Process ID (PID) Using netstat
Using the nestat command we can find the process ID (PID) for a specific port. In a terminal type the following and replace the “<port-number>” with our port number.
This generates output that looks like this:
In the output above the PID (process ID) is the ninth value (the fourth value from the end), in this example output the process ID (PID) is “63851”. This command will also print out the port number, which is 9999 in the above output example. How to use indesign cs6.
Find the Process Name
We can now use the process status command ps to display the process name for the process ID (PID).
This generates output that looks like this:
In the output above the process name is the last value “the-process.” Now we know the name of the process that is listening to the port. The reason as to why the grep command is listed twice is to avoid displaying the process ID (PID) for the grep command itself.

How to Kill or Stop the Process by PID
You can kill the process by process ID (PID) using the kill command. Replace “<PID>” with the process ID from lsof or netstat.

The lsof command lists open files. Network sockets count as files, so each open network socket, either listening or actively in use is listed by lsof. In addtion you can run the man lsof command to display all the different options for lsof.

lsof can take a very long time to execute, so I suggest that you use -n (inhibits the conversion of network numbers to host names for network files) and -P (inhibits the conversion of port numbers to port names for network files) to speed it up.
