NASA Multimedia

Although not everyone, a few of us must definitely have dreamed of becoming an astronaut or are still fascinated by the facts of outer space. Fascination could have very well led to curiosity and in that process, anything associated with space reminds us of NASA.

So, if you are one of those space buffs looking for some fun time, the Multimedia section of NASA’s official website has some cool and interesting stuff ranging from images, videos, televised events, podcasts, videocasts, blogs, 3D resources and more.

RSS feeds are available for all the multimedia features as well as mission specific news. Updates can also be received via E-mail.

The one I like most is the NASA Image of the Day feed – one stunning image a day with description attached and available for download in different resolutions.

Here’s today’s image:

Unzip multiple zip files using Shell script

For the Linux newbie from a noob

Scenario: You have quite a large number of zip files in a folder with other files and would like to avoid manual labor of extracting one file at a time.

Solution: A simple shell script to extract all files at one go.

Save the script with a .sh extension and make sure it resides in the same directory as the compressed files.

Fire up the terminal, cd to the target directory and execute the script using ./xxxx.sh
