New ebook helps Leopard users manage permissions in order to solve
problems, increase privacy, and share files better.

Ithaca, NY USA (February 25, 2008) — Mac users who have long been at the
mercy of arcane permissions from Mac OS X’s Unix underpinnings can now
regain mastery of their Macs with “Take Control of Permissions in Leopard,”
the latest Leopard-specific title in the Take Control library. Written by
Unix guru and Mac aficionado Brian Tanaka, the 87-page ebook mixes
practical how-to details and troubleshooting tips with just the right
amount of theory as it explains permissions in relation to how you keep
your files private, copy files to and from servers effectively, set the
Ignore Permissions option for external disks, repair screwy permissions,
and delete those files that just won’t die.
The ebook may be purchased for $10

For those who want to learn advanced concepts, the ebook also delves into
topics like the sticky bit, symbolic versus absolute ways to set
permissions, and how to work with bit masks. In particular, Tanaka looks at
what’s new with permissions in Leopard, including the disappearance of the
NetInfo database and the increased use of access control lists. The book
covers managing permissions from the Finder’s Get Info and Inspector
windows, with more-capable third-party utilities, and from the Unix command

Take Control publisher Adam Engst said, “I’m no Unix expert, but with
Brian’s clear explanations, I’ve been able to handle a wide variety of
permissions-related issues on my Macs. With this information, we Mac users
don’t have to feel like guests on our own Macs any more.”
