How to create alias to kill processes running on a TCP/IP port?

Question

What I have:

alias killport='sudo kill -9 `sudo fuser -n tcp $1 2> /dev/null`'

Problem:

Running e.g. killport 8000 doesn't appear to work, though. However, simply running...

sudo kill -9 `sudo fuser -n tcp 8000 2> /dev/null`

... DOES work. I can't figure out where I'm messing up.

The major difference between the working and non-working versions as far as I can see is that the aliased version involves a variable, and is executed by the shell for me.... But maybe someone has seen this kind of problem before and knows right where to look.

Bash Aliases do not support arguments. Use a function – iruvar Sep 27 '13 at 21:52 — iruvar, Sep 27 '13 at 21:52
Hm. Well, that'd do it. I guess I'll just write a script. – Brian Peterson Sep 27 '13 at 21:53 — Brian Peterson, Sep 27 '13 at 21:53

You should use a function instead an alias, becaue aliases don't support parameters, make something like that:

killport(){ 

sudo kill -9 $(sudo fuser -n tcp $1 2> /dev/null);

}

Now put this function in your bash configuration file, eg ~/.bashrc and then run:

source  ~/.bashrc

And you're done
