Shell script to execute rcon commands

I wrote a simple Bash script which executes commands over rcon.
It uses some Bash-specific features so I doubt it'll work on other shells.

Maybe it's useful, maybe it isn't, anyway here it is:

example usage:

Code:

./rcon.sh -host=localhost:26000 -pw=password -secure=2 -c status 1
