Where are the CRON logs?

Question

Where are the CRON logs located?

Answer

The CRON logs are located in the /var/log/ directory and are named cron. The CRON logs rotate, so they could also be found having a date at the end.

[root@server ~]cPs# ls -lah /var/log | grep cron
-rw------- 1 root root 592K Jun 9 00:04 cron
-rw------- 1 root root 1.3M May 16 03:19 cron-20210516
-rw------- 1 root root 1.3M May 23 03:47 cron-20210523
-rw------- 1 root root 1.4M May 30 03:40 cron-20210530
-rw------- 1 root root 1.5M Jun 6 03:16 cron-20210606

You can also grep the systemd journal for CRON entries.

[root@server ~]cPs# journalctl  --since yesterday --no-pager | grep cron
