Hello,

I guess you're trying to do cicada -c 'echo $HOSTNAME' instead.

By cicada echo $HOSTNAME, you are actually running the echo file as a script, passing a param $HOMENAME.

If you replace cicada with bash, you would get an error msg: /bin/echo: cannot execute binary file, which is better one. I will try align cicada with bash in such case. Thanks for report!
