I was playing around cron and the following command
worked fine I think.
Then I installed gnome-schedule and didn't like it too much ..
so I removed it and run again
but nothing was shown, while I had a default crontab file before
and then I noticed that the above command opened a temporary file instead like
I tried to edit it with nano, but when I save it of course nothing is changed on my system because its a temporary file.
I searched for /etc/cron.allow or /etc/cron.deny but they don't exist.
What can be changed installing gnome-schedule and how can I turn my system back in order to be able to use crontab -e again?
Thank you for any suggestion
