Open Vim to add your cronjobs.

crontab -e

Setting the format:

* * * * * command
* - minute (0-59)
* - hour (0-23)
* - day of the month (1-31)
* - month (1-12)
* - day of the week (0-6, 0 is Sunday)
command - command to execute
(from left-to-right)

Then in Vim, you can write an expression like 0,15,30,45 * * * * cd ~/.scripts && ./work.sh.

To see active jobs, run crontab -l.
