Hel with easy bash script

[Ballena]

Thanks for the answers guys! I'm almost there.

#!/bin/bash

case $1 in
start)
  echo 'Startning irctor...'
  /home/erikw/.screen-start.sh
  ;;
stop)
   echo 'Stopping irctor...'
   screen -S irctor -X quit
   ;;
NOTHING)
   echo 'Attaching irctor...'
   screen -x irctor
   ;;
esac

The only problem is that NOTHING is suppose to be just nothing which means no parameter/argument at all. How do I achive that? I have really no idea..

Thanks.



Edit.
Maybe you should put everything in a if statement that checks if any arguments exists: but I have no idea about how to make that either :/


Edit 2.
I got some answers on some IRC channels. NOTHING shall be replaced with "" which makes the problems solved!
