Which command edits the crontab for the current user?

• A. crontab -l
• B. crontab -e
• C. crontab -r
• D. crontab -u

Answer: (B)

Editing your own scheduled tasks is done by launching the crontab editor for the current user. The command crontab -e opens your personal crontab in the system’s default editor so you can add, modify, or remove jobs. When you save and exit, the new schedule is installed and will start running according to the defined times.

The other crontab options perform different actions: listing shows the current contents, removing deletes the entire crontab, and using a user specification with -u targets a different user’s crontab (which typically requires elevated privileges).
