Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Secure Locate provides a secure way to index and quickly search for all files on your system regardless
of ownership. It uses incremental encoding just like GNU locate to compress its database to make search-
ing faster, but it will also check file permissions and ownership before displaying matched entries so
that users will not see files they do not have access to
Presumably that would imply that if the file no longer exists then the user would not have access to it and it would not be displayed.
No If you delete a file, it remains in slocate.db until the next update. That said, if you subsequently searched for that deleted file, locate (slocate) checks for physical existence, because that file no longer exist, it's entry in slocate.db will be removed. In this case the database is updated.
FYI, with a default, normal install of Slackware, updatedb is run daily at 0440 via a cron script in /etc/cron.daily/
