Ah, sorry, I misunderstood. You'll need to wrap the call to dirvish with
a test. That is, write a script that does a test and then calls dirvish
and put that script in your crontab. You could test for:
- a running dirvish process
- one of the temporary files in the active image (e.g. log.tmp)
- you could create your own lock file before running dirvish and remove
it afterwards, and test for the existence of that.
