On Monday, January 21st at 18:30, Haifux will gather to hear a talk by
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.
