Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Write the script, then make it executable, then add a crontab entry with daily schedule, then verify with crontab -l
Setting up a cron job correctly involves first writing the script that will be executed, then making it executable with chmod +x, then adding a crontab entry using crontab -e with the correct time specification (e.g., '0 0 * * *' for daily at midnight), and finally verifying the job is listed with crontab -l. This order ensures the script is ready and permissions are set before cron attempts to run it, and verification confirms the entry is valid.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Write the script, then make it executable, then add a crontab entry with daily schedule, then verify with crontab -l
Why this is correct
This is the correct order because the script must exist before making it executable, and the crontab entry requires an executable script. Verification ensures the job is active.
- ✗
Write the script, then add a crontab entry with daily schedule, then make it executable, then verify with crontab -l
Why it's wrong here
This is incorrect because the script must be made executable before the crontab entry is added; otherwise, cron will fail to run the script due to permission issues.
- ✗
Make the script executable, then write the script, then add a crontab entry, then verify with crontab -l
Why it's wrong here
This is incorrect because you cannot make a script executable before it exists; you must write it first.
- ✗
Add a crontab entry with daily schedule, then write the script, then make it executable, then verify with crontab -l
Why it's wrong here
This is incorrect because the crontab entry references a script that does not exist yet, and the script must be written and made executable before the cron job can run it.
