You can put that code cd path/to/myapp; /usr/local/bin/mix hello.greeting inside a shell script (something.sh) give +x permission (chmod +x something.sh) and then call it on the crontab. Don’t forget to use full path instead of relative paths.

It works perfect, thanks for your help, Really wonderful community.
