Crontab is a time-based job scheduler in Unix-like operating systems. It allows users to schedule commands or scripts to run at specific times or intervals. Checking crontab is essential for ensuring that scheduled tasks are running as expected and for troubleshooting any issues that may arise.
There are several ways to check crontab. One common method is to use the “crontab -l” command. This command lists all of the crontab entries for the current user. Another method is to use the “crontab -e” command. This command opens the crontab file in a text editor, allowing the user to view and edit the entries.
