Command-line utilities: Tips and tricks<br>
<br>
Abstract<br>
<br>
Command-line utilities is the real power of a Linux computer, and yet<br>
there's always a few useful utilities that even an experienced Linux<br>
user doesn't know about. This meeting is dedicated to going through<br>
several random utilities, some of which are less known, others are known<br>
but have surprising possibilities.<br>
<br>
The range goes from things as simple as using "touch" to fake a<br>
modification date to using ssh for surfing the web (with your browser)<br>
as if your computer was in another country.<br>
<br>
No previous knowledge is required. Even though newbies will gain the<br>
most of this meeting, there is also room for those more familiar with<br>
the shell prompt. Those who want to take the stand for a few minutes to<br>
talk about a utility are welcome, of course.<br>
<br>
There will be no slides during this meetings, just a shell window for<br>
demonstrations.<br>
<br>
This is a list of topics that may or may not be covered, depending on<br>
interest and what time allows. Some will be mentioned in a few words,<br>
and we may spend some time with others.<br>
