How to set crontab when using AWS CloudFormation Userdata?

I am setting

(crontab -l ; echo \"0 * * * * wget -O - -q http://www.example.com/cron.php\") |          


        

Answer 1

To do this properly you should do the following inside the bash script:

crontab -l > /tmp/mycrontab
echo '0 * * * * wget -O - -q http://www.example.com/cron.php' >> /tmp/mycrontab
crontab /tmp/mycrontab
