I can login to nano or vi through Putty to my web server.
After opening nano editor by typing crontab -e, I enter the following.
# m h dom mon dow command (this comes up always at the top) */30 * * * * wget -q -O /dev/null http://mywebsite.org/admin/cron.php
However I am uncertain what I need to do after this.
Q1. Do I need to save it? If so, how to save this file?
I can't find any command to save. There are ^Get help, ^Writeout etc.
At the top of the screen, it says the following. GNU nano 2.0.7 File: /tmp/crontab.Q1SgwM/crontab
Q2. Is this the place where this cron is stored? Then how can I open it if I want to edit/change?
Q3. Is that all I need to do? Is the cron starting automatically?
Thanks in advance.
