Eli Billauer:

    Command-line utilities: Tips and tricks

Abstract

Command-line utilities is the real power of a Linux computer, and yet 
there's always a few useful utilities that even an experienced Linux 
user doesn't know about. This meeting is dedicated to going through 
several random utilities, some of which are less known, others are known 
but have surprising possibilities.

The range goes from things as simple as using "touch" to fake a 
modification date to using ssh for surfing the web (with your browser) 
as if your computer was in another country.

No previous knowledge is required. Even though newbies will gain the 
most of this meeting, there is also room for those more familiar with 
the shell prompt. Those who want to take the stand for a few minutes to 
talk about a utility are welcome, of course.

There will be no slides during this meetings, just a shell window for 
demonstrations.

This is a list of topics that may or may not be covered, depending on 
interest and what time allows. Some will be mentioned in a few words, 
and we may spend some time with others.
