Bash Script for Reading Some Feeds

Bahwa nge-blog di blogspot atau blogger menyediakan fasilitas built-in bagi pengunjung kita untuk membaca update blog kita dengan menggunakan fasilitas RSS, so seringkali juga hal tersebut kita gunakan untuk mendaftarkan blog kita di beberapa search engine terkemukan, fasilitas tersebut terletak di URL http://yourblog.blogspot.com/feeds/posts/default.

dan ternyata bash pun bisa untuk membaca Feeds... ini scriptnya...

#!/bin/bash

declare -i count
ver=0.4
choise=endless
browser=none

#
# RDF/RSS reader
#
# Pretty lame actualy..
# Could have used some functions instead of c-and-p
# Might make it to smallest rdf/rss reader
# For updates check http://etv.cx/~the_jinx/rssread
