- ### Or Kill node process running under certain port.

Goto the command line and find the `"PID"` of the process:

```
$ lsof -i tcp:8000 //where the port you want to kill is 8000
```

 The above command opens a list of all processes with their `"PIDs"`.

```
...
COMMAND  PID    USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
node    7069 chidera   20u  IPv6 891480      0t0  TCP *:8000 (LISTEN)
node    7069 chidera   22u  IPv6 892242      0t0  TCP localhost:8000->localhost:39292 (ESTABLISHED)
...
```

 From the output, the unique `PID` of my process on PORT 8000 is `"7069"`,

```
node    7069 chidera   20u  IPv6 891480      0t0  TCP *:8000 (LISTEN)
node    7069 chidera   22u  IPv6 892242      0t0  TCP
```

Finally, Kill the process using it's `"PID"` like so

```
$ kill -9 7069
```

 Alternatively, you could kill all node processes using

```
$ pkill node
```
