Mock exam 3 Question 2

[znop0505]

Hello. I gave the answer:
0 4 15 * * Mary find /home/mary/ -typed -empty -delete

The solution does not specify a user.
Only the “su - mary …” command. Why? This is a system-side cron table.
How to answer correctly in the exam? Specify user Mary or su - mary …"?

The solution is invalid (when system-wide crontab is considered, the username has to be specified as the 6th field). You solution is “correct-ish”, because no user names can begin with a capital letter.
