In a Linux system, crontab execution logs are typically recorded in the /var/log/cron or /var/log/syslog files. You can view crontab execution logs using the following command:

  1. Check the file /var/log/cron:
  2. Display the contents of the cron log located at /var/log/cron.
  3. View the /var/log/syslog file:
  4. Display only lines in the syslog that contain the word “CRON” by using the command: cat /var/log/syslog | grep CRON.

The above command will display the execution status of each crontab task, including the execution time and results. If you want to view the logs in real-time, you can use the tail command:

tail -f /var/log/cron

Please note that the location of the cron log file may vary in different Linux distributions, such as /var/log/cron.log or /var/log/cron/cron.log. If the above command cannot find the log file, try checking other possible locations.
