RHEL Linux - Red Hat System Administration Practice Exam

To view currently scheduled cron jobs for a user, the most appropriate command is `crontab -l`. This command is designed to list the contents of the user's crontab file, which contains the scheduled tasks for that specific user. When executed, it displays the cron jobs, showing the timing and the associated commands that are set to run.

Using `crontab -l` is the standard way to check active cron jobs without altering them, making it an essential tool for users managing their scheduled tasks. This command is straightforward and serves its purpose effectively, aligning directly with the need to view rather than edit or manage.

The other options do not provide the same functionality. For example, running `crontab --list` is incorrect because the proper syntax for listing the crontab is with the `-l` flag. The command `crontab -e` is used for editing the crontab, which would potentially change the scheduled tasks rather than simply listing them. Lastly, `cronjobs -l` is not a valid command in the Linux command set related to cron jobs. Since these alternatives do not serve the function of listing current scheduled cron jobs, they reinforce the correctness of the `crontab -l`
