I started a crontab job in a server remotely (in a screen session) from a local machine. Days later, I terminated the screen session and restarted my local machine. The cron job in the server is still running (I'm sure about this). But using crontab -l will show
"no crontab for xxx"
Nor does crontab -r deletes the job. So is it kind of zombie now? How do I manage it?
