Rails server says port already used, how to kill that process?

Question

I\'m on a mac, doing:

rails server

I get:

2010-12-17 12:35:15] INFO  WEBrick 1.3.1
[2010-12-17 12:35:15] INFO  ruby 1.8.7 (         


        

Answer 1

Type in:

man lsof

Then look for -w, -n, and -i

-i: internet stuff -n: makes it faster -w: toggles warnings

There are WAY more details on the man pages
