cron usage and squid daily log rotate

[a bv]

Thank you very much,

But what all these mean one by one? weekly tells it self (what needed
is daily logs so will change the weekly to daily) but what about the
other lines and  what about my log files are not at the default path?
Is there something to care /change at squid.conf for this log rotation
thing?

weekly
   rotate 5
   copytruncate
   compress
   notifempty
   missingok

Regards
