Terminal command doe not work

I want to use AnyBar to show different colors in the menu bar when a key is pressed. For this I created the trigger as shown in the attached screenshot. After

$ open -a AnyBar

I tried

Excute Terminal Comman (Asyn, ..)
Excute Terminal Comman (Synchronous, ..)
Execute Shell Script ...

but does not work. What am I missing her? Any help would be appreciated.

Always use the full path to the command line tools:

echo -n "red" | /usr/bin/nc -4u -w0 localhost 1738

Thanks. I should have read small prints :wink:
