Linux CLI - Cron and Scheduling

You added this line in crontab -e:
60 12 * * * /home/user/script.sh

BHour 12 is invalid; hours range 0-11.

CMinute value 60 is invalid; minutes range 0-59.

DMissing day-of-week field causes error.

Step-by-Step Solution

Step 1: Check the minute field validity
Minutes must be between 0 and 59. 60 is invalid and causes cron to ignore the job.
Step 2: Verify other fields
Hour 12 is valid (means noon). Day-of-week is optional. Script path is absolute.
Final Answer:
Minute value 60 is invalid; minutes range 0-59. -> Option C
Quick Check:
Minute must be 0-59, 60 is invalid [OK]

Quick Trick: Minutes max at 59, not 60 [OK]
