Cron jobs are also known as scheduled jobs. After adding several of them, you might want to identify what jobs have been added. The following command helps.
[[email protected] cron]# crontab -l
It will result in something as below.
* * * * * cd /etc/init.d/; ./rhq-agent-wrapper.sh startWhere the first * is minute field, second * is hour field, third * is day of the month, fourth * is month field, fifth * is day of the week and the text after the * is the command to be executed.Ex: * 1 * * * cd /etc/init.d/; ./rhq-agent-wrapper.sh start
In this example, the command will be executed at 1 a.m. every day.
