Question: When I am starting rails server using `rails s` command it is showing `A server is already running. Check C:/Sites/folder/Pids/Server.pids`

When I open the file it is outputting a 4 digit number only so how could I resolve this issue ? 

**FYI**

1. No other instance of Rails cmd is running this time.
2. Checked Task manager but only `cmd.exe` is showing no else process is running. (using Windows).

Answer: 
```
kill -9 $(lsof -i tcp:3000 -t)

```
`gem install shutup`

then go in the current folder of your rails project and run 

`shutup` # this will kill the Rails process currently running

You can use the command 'shutup' every time you want

DICLAIMER: I am the creator of this gem

NOTE: if you are using rvm install the gem globally 

```
rvm @global do gem install shutup

```
