Logrotate
To avoid too many log files on the USB storage device you can use logrotate to remove the files automatically.
opkg install logrotate
No LuCi app for logrotate is available everything must be setup on CLI.
The directory where logrotate scripts are maintained is /etc/logrotate.d.
You can easily add a new logrotate script for adblock
nano adblock-log
/mnt/sda1/adblock/reports {
rotate 4
daily

compress
delaycompress
sharedscripts
endscript
}
