Using ‘httrack‘ is easy, as it has built-in wizard that can guide you through the process of mirroring web sites. The user will be asked a series of question about the URL to be mirrored, the location where the files will be saved, proxy server and the user-agent to be used.

p/s: httrack perhaps is the only open-source website copier/downloader tool available for GNU/Linux operating system. It is efficient and easy to use. The only gripe that I’ve when using ‘httrack‘ is that it does not provide progress feedback (unlike its counterpart in Microsoft Windows) like ‘wget‘

Linux Package Manager Cheat Sheet Reference Chart

Linux comes in many flavors or distros, and each distro handles software installation differently from one another. Most GNU/Linux distro uses a package management system to manage software updates/instalation/removal in order to help users administer their Linux systems.

However, many of these package management system has different interface and commands, as such users from Ubuntu (or Debian based) might only be familiar with ‘apt’ or dpkg while Fedora (Red Hat based) users might only familiar with yum and rpm, which may create confusion when users from either distro were to exchange environments.

Luckily, somebody was kind enough to provide these users with Linux Package Manager Cheat Sheet which act as a reference point whenever a user had to switch to another distro which uses package management that are not familiar with them.

The package management software listed are for: apt,dpkg,yum, rpm, pkg* (slackware based) and AIX-based lsl**.
