i have inserted on my cron the lines below to make some backups but isn't working. I cant find where is the cron log file to see what is going wrong. Anybody can help?

My crontab:

@reboot sleep 10; mount -a -t cifs; //Works to mount my samba shares

00 23 * * * /usr/local/groovy-1.5.6/bin/groovy /mnt/ecmsrv/u/redes/scripts/groovy/backupGeral.groovy;

30 23 * * * /usr/local/groovy-1.5.6/bin/groovy /mnt/ecmsrv/u/redes/scripts/groovy/backupSisCDI.groovy;

this commands works fine on shell.

Ty all.
