# Find The Process Using A Specific Port
|
|
|
|
The `netstat` utility is often recommended for finding the PID (process ID)
|
|
bound to a specific port. Unfortunately, Mac's version of netstat does not
|
|
support the `-p` (process) flag. Instead, you'll want to use the `lsof`
|
|
utility.
|
|
|
|
```bash
|
|
$ sudo lsof -i tcp:4567
|
|
```
|
|
|
|
Running this will produce a nicely formatted response that tells you several
|
|
pieces of information about the process bound to `:4567` including the PID.
