17.You have entered the following cronjob. When will it run?
15 * * * 1. 3. 5 myscript

At 15 minutes after every hour on the 1st, 3rd and 5th of each month.
At 1:15 am, 3:15 am, and 5:15 am every day.
At 3:pm on the 1st, 3rd, and 5th of each month.
At 15 minutes after every hour every Monday, Wednesday, and Friday.

Explanation: The order of the time fields is:

minute (0-59),
hour (0-23),
day of the month (1-31),
month of the year (1-12),
day of the week (0-6 with 0=Sunday).

The 15 means 15 minutes past. The first asterisk means every hour. The third asterisk means every month. The second asterisk means every day but the job won’t run every day. This is because the 1.3.5 in the ‘day of the week’ field means Monday, Wednesday and Friday. Therefore, the job will run on every Monday, Wednesday and Friday at 15 minutes past every hour. Myscript is the name of the script that will run at the specified times.
