You can check out my answer to this similar question

Basically, I've included there a bash script named "runEvery.sh" which you can run with cron every 1 minute and pass as arguments the real command you wish to run and the frequency in seconds in which you want to run it.

something like this

* * * * * ~/bin/runEvery.sh 5 myScript.sh
