Good news for all those interested in astronomy and space science. I've created a silly little bash script called 'iss' that gets you the following information right in your terminal,
  • Current position of International Space Station (ISS) in latitude-longitude. And if map data is available for the current location then the script will display name-address of the location.
  • Passing date-time and duration of ISS for your location.
  • Number of people currently in space, their name(s), and the name(s) of spacecraft they are on.
Sounds interesting? Only dependency of this script is 'jq'.
Code: [Select]
sudo apt-get install jq

Here is the script 'iss',

Save the script 'iss' somewhere in your $PATH and 'chmod 755' it. You need to add values to a few variables in the script before using it. First variable is 'latit'. Assign the latitude of your location to it. The second variable is 'longi'. Assign the longitude of your location to it, Last variable is 'eleva'. Assign the elevation (in meters) of your location to it. Save the changes. Where do you get the latitude-longitude-elevation for your place? Easy! Just go to the following website and search for the laitude-longitude-elevation of your location,

HeavensAbove - Location selector

Type 'iss' in your terminal, hit enter and have sum astronomical fun!
Looking forward to your feedback on this script.
Cheers!!!
