mint is not turned on by default cron logging
1. Modify rsyslog
sudo vim /etc/rsyslog.d/50-default.conf
cron.* /var/log/cron.log
# The cron front uncommented
2. Restart rsyslog
sudo service rsyslog restart
3. Check the crontab log
sudo tail -f /var/log/cron.log
The default cron will send mail to operating results of the task such as sending an error message to the user's mailbox system, and information specific script output does not appear in the log, so we can specify what log output path of each task:
＃0 2 * * * db_backup task; >> /var/log/db_backup.log 2>&1
*/1 * * * * /bak/bkmysql.sh
cat bkmysql.sh
#!/bin/bash
User="root"
Password="admin"
Database="test"
Dir="/bak/mysql"
Date=`date +%Y%m%d_%H%M%S`
sudo mysqldump -u$User -p$Password $Database|gzip >$Dir/$Database.dump_$Date.sql.gz
