I'm not successful with the Terminal.
My 10.2.8 don't know the command: sudo periodic daily
Please, can you tell me, what's there wrong. I can't find the solution.

    Hi !

    Mac OS X v. 10.2 should be able to use this command without any issue — unless, of course, some of the necessary files have been manually removed.

    You may want to make sure that the following files and folders exist :

    [Hard drive] -> private -> etc -> periodic -> daily
    [Hard drive] -> usr -> sbin -> periodic
    [Hard drive] -> usr -> bin -> sudo

    Would all of them exist, your Mac should be able to perform the command. You may want to make sure that you entered the command without any typo — for example, spaces at the end of the line or two spaces between the words.

      i found your maintenance tips to be very useful and informative. but i do hv a question. instead of running those maintenance tips (forced periodic maintenance) via Terminal, would i be able to attain the same efficacy if i were to use software utilities that do the same functions? a utility like Brian Hill's MacJanitor, perhaps, which can be found at

        Hi !

        First of all, thanks for the kind words, I really do appreciate them !

        When it comes to performing such basic tasks, I usually prefer to use the Terminal since it doesn't require me to install a third-party application and gives me more flexibility.

        However, you're right : there are some good utilities that perform these tasks with a nice interface — most of them simply run an AppleScript™ that executes the same commands.

        Unfortunately, I cannot comment on their features but, as long as they run the exact same commands, they should have the same effects.

        You may want to perform a search in a Mac-related forum to gather some more information about the various options. The AppleCare discussion forums ( ) are, in my experience, the best place to find such answers.

          Hallo, I should note this O'Reilly Network article on regular maintenance for Panther for future reference. In two ebooks I have not once repaired permissions or forced periodic maintenance in OS X

      Whitespace is allowed in any place on the line (that includes after and between command options parameters), the only exclusion to this rule is within filenames (which would need to be either quoted or the space escaped). The following are functionally identical:

      ls file\ with\ spaces
      ls file\ with\ spaces
      ls "file with spaces"
      export $A_SPACE=" " # or setenv A_SPACE " "
      ls ${A_SPACE}${A_SPACE}${A_SPACE}file\ with\ spaces${A_SPACE}${A_SPACE}

        Sorry .. that should read:
        export A_SPACE=" "

        (and some of the other "spaces" were cut by whatever parses the text area .. still the last example should be clear enough).
