I don't know how effective or worthwhile the cron updates are, but I know that I've used Maintenance/Yasu for almost 2 years now and never had a problem with my G5 here at work. Really all most people do is "repair permissions" and that's sufficient. Yes, or use a program like Yasu if you shut it off routinely. * By default, the monthly script is scheduled to run on the first of the month at 05:30 hours local time. * The output from the monthly script is written to the /var/log/monthly.out file, which can be viewed in Console. * The monthly script reports per-user usage accounting and rotates - depending on the version of Mac OS X you are using - the wtmp, install.log, and cu.modem.log files. O Under Panther and Jaguar: 04:30 hours local time. * By default, the weekly script is scheduled to run every Saturday at the following times: * The output from the weekly script is written to the /var/log/weekly.out file, which can be viewed in Console. * The weekly script rebuilds the locate and whatis databases and rotates - depending on the version of Mac OS X you are using - the following log files: ftp.log, lookupd.log, lpr.log, mail.log, netinfo.log, ipfw.log, ppp.log, and secure.log * By default, the daily script is scheduled to run daily at 03:15 hours local time. * The output from the daily script is written to the /var/log/daily.out file, which can be viewed in Console.
Under Tiger, the daily script also cleans up scratch fax files and prunes asl.log, the log for the new Apple System Logging facility. * The daily script removes old log files, "scratch" and "junk" files, backs-up the NetInfo database, reports a variety of system and network statistics, and rotates the system.log file.
Each maintenance script - daily, weekly, and monthly - has a specific function.
