I have some tasks which I have configured in Manjaro through cronie. I am sending the logs perfectly by mail (I put that MAILTO line into my cron file).
But, is it possible to have both options, i.e., logs being sent by email and also recorded in a file?
All the output is also saved in the journal. The journal is not a textfile, but you can access the journal with the journalctl command.
If you really want, you could even install a syslog program to pipe your journal messages to a real text file. This would not my first choice, but if you need it.
