Linux

I like to start by following these guides, with a few short cuts and additions:

The Perfect Desktop - Fedora i686 (GNOME)

This is a great screen by screen guide to help you download and install Fedora

After installing Fedora 14 the big short cut is to use easyLife, download and install easyLife for Fedora here.  This provides one application that you can use to add all the "not completly opensource" stuff you really need to make Fedora useful.  Things like the following list are just a couple of clicks away:

• Sets "sudo" command up for your regular user;
• Configures RPMFusion repository for extra and non-free software;
• Installs Flash Player plugin;
• Installs all kinds of Codecs (h264,divx,xvid,mp3 etc);
• Installs nvidia drivers;
• Installs Skype;
• Installs Sun Java and Sun Java Plugin for Firefox;
• Integrates Sun Java with system-switch-java;
• Installs Google apps (Picasa, Desktop);
• And many others...

GUI Administration Tools

For some reason several items I am used to having needed to be added manualy to this Fedora release.  For example to use graphical tools for administration I had to run the following commands and then choose 'y' to install the GUI utility.

To allow the starting stoping and configuring of services:

system-config-services

Tips on how to set up Ubuntu and some useful tips.

The state of the Linux desktop

I'm a fan of Fedora and Ubuntu, but for different reasons. Fedora, while unpolished, is a solid distro for adventurous Linux users and developers who want to be on the bleeding edge. Power users deserve a good distro that is usable and feature-complete without a lot of polish or distraction - and that's what Fedora is.
Ubuntu is the flip side. It's very polished, closing in on Apple in terms of usability and applications. It's not quite there yet, but getting closer and certainly a persuasive distro for people switching from Windows. If you're looking to get a friend started with Linux, don't hesitate to begin with Ubuntu.

To add this repo:

wget http://rpms.famillecollet.com/remi-release-11.rpm
rpm -Uvh remi-release-11.rpmwget http://rpms.famillecollet.com/remi-release-11.rpm
rpm -Uvh remi-release-11.rpm

To update Firefox, you must enable the repo, as it is disabled by default

yum --enablerepo=remi update firefox

To get a list of all available php modules, use this command (as root):

yum list | grep php-

You use rsync in the same way you use rcp. You must  specify  a  source and a destination, one of which may be remote.

rsync -avz foo:src/bar /data/tmp

rsync -av /var/samba/ server:/opt/samba  # no compression
 

Webmin Cpanel like open source web control panel for your server

by default it is installed on port :10000

grep command syntax

grep "text string to search" directory-path
Examples

To search for a string called redeem reward in all text files located in /home/tom/*.txt directory, use

$ grep "redeem reward" /home/tom/*.txt

To recursively search for a text string all files under each directory, use -r option:

$ grep -r "redeem reward" /home/tom

find command syntax

$ find path expression

Using the command line, you can search for files larger than a given filesize using

$find path -size +1024k

$find path -size +5M -print

Note the -print is the default and assumed

Using the command line, you can search for files with name

$find path -name '*.AVI'

Find all files with the name program.c starting at root directory (i.e / directory)

$ find path -name 'program.c' 2>/dev/null

$ find path -name 'program.c' 2>errors.txt

Note : 2>/dev/null  in case any error messages '2' pop up simply send them '>' to /dev/null i.e. simply discard all error messages.

To show details on the CPU:

# more /proc/cpuinfo
