How to extract zip files on Linux?

May 28th, 2018 No comments

One of my students who switched to Linux recently asked this question. There are many utilities with GUI for handling archives, but it’s better done with a terminal command.

  1. Start a Terminal.
  2. If “unzip” utility is not installed, try this command to install it. (on Debian Linux distributions and its derivatives, Ubuntu, Linux Mint etc.)

    sudo apt-get install unzip

  3. We want to unzip a file named “” in my “home” directoryunzip
  4. Type the command as follows


  5. It will extract the archive in the same directory, with the name of zip files as directory name  unzip

Thanks Ashwin for bringing up with this question !

Few invites left for Diaspora, the open source “Facebook killer”

December 20th, 2010 2 comments


Diaspora is a "privacy-aware, personally controlled, do-it-all distributed open-source social network". It’s a decentralized alternative to social network services like Facebook. Diaspora works by letting users set up their own server, like a hosted wordpress installation, to host content; pods can then interact to share status updates, photographs and other social data.

diaspora It’s your data and you ought to be controlling it. Diaspora is to allow participants to retain ownership of all the material they use on the site, and retain full control over how that information is shared. It categorizes the social connections into individual groups called Aspects, and the user can control which groups see which material.


Diaspora lets you sort your connections into groups called aspects. Unique to Diaspora, aspects ensure that your photos, stories and jokes are shared only with the people you intend.



You own your pictures, and you shouldn’t have to give that up just to share them. You maintain ownership of everything you share on Diaspora, giving you full control over how it’s distributed.



Diaspora makes sharing clean and easy – and this goes for privacy too. Inherently private, Diaspora doesn’t make you wade through pages of settings and options just to keep your profile secure.

In short it’s the social network which respects your privacy the most.

The Alpha version of Diaspora is out !
