There are some process which does not shown using normal netstat command, so you have to check it using <code>sudo</code>.

Do <code>sudo netstat -lpn |grep :8080</code>. Process running by system does not show PID, to get PID of this process you will have to run it using <code>sudo</code>

And then killl the process using port <code>8080</code>. You may have to use <code>sudo</code> here as well. So to kill this process use <code>sudo kill -9 PID</code>

To kill the process based on port first we have to find out the relevant pid for given port and kill using that pid,

In my case i wanted to get the pid(process id) of 3000 port:

<pre><code>netstat -ltnp | grep -w '3000'
</code></pre>

then find pid which is listening to tcp

<pre><code>tcp6 0 0 :::3000 :::* LISTEN 29972/node 
</code></pre>

you will get pid 29972

To kill this pid use below command

<pre><code>kill -9 29972
</code></pre>

pseudo code for kill process based on port

<pre><code> netstat -ltnp | grep -w 'PORT'
</code></pre>

and

<pre><code>kill -9 PID
</code></pre>

I am trying to kill a process in the command line for a specific port in ubuntu.

If I run this command I get the port:

<pre><code>sudo lsof -t -i:9001
</code></pre>

so...now I want to run:

<pre><code>sudo kill 'sudo lsof -t -i:9001'
</code></pre>

I get this error message:

<pre><code>ERROR: garbage process ID "lsof -t -i:9001".
Usage:
 kill pid ... Send SIGTERM to every process listed.
 kill signal pid ... Send a signal to every process listed.
 kill -s signal pid ... Send a signal to every process listed.
 kill -l List all signal names.
 kill -L List all signal names in a nice table.
 kill -l signal Convert between signal numbers and names.
</code></pre>

I tried <code>sudo kill 'lsof -t -i:9001'</code> as well
