Displaying crontab Files

The crontab -l command displays the contents of a crontab file much the same way that the cat command displays the contents of other types of files. You do not have to change the directory to /var/spool/cron/crontabs directory (where crontab files are located) to use this command.

By default, the crontab -l command displays your own crontab file. To display crontab files that belong to other users, you must be superuser.

How to Display a crontab File

Before You Begin

Become the root user to display a crontab file that belongs to root or another user.

You do not need to become root to display your own crontab file.

• Display the crontab file.

  # crontab -l [username]

  where username specifies the name of the user's account for which you want to display a crontab file. Displaying another user's crontab file requires superuser privileges.

  ---

  Caution - If you accidentally type the crontab command with no option, press the interrupt character for your editor. This character allows you to quit without saving changes. If you instead saved changes and exited the file, the existing crontab file would be overwritten with an empty file.
