Bash Scripting.

This is an open series in which Hacker Public Radio Listeners can share their Bash scripting knowledge and experience with the community. General programming topics and Bash commands are explored along with some tutorials for the complete novice.

This is a response show to hpr3959 :: Download any HPR series with english file names "A dir with the series name will be created and all shows will be renamed to ShowTitle.mp3 inside it"

This was the first show by gemlog and he used Bash, sed, grep, wget, to scrape the HPR site. This is great but as he points out any change to the site will break the script.

A safer way to get the episodes is by scraping the rss feed, and the following is an example of how you might do that



wget "${series_url}" -O - | xmlstarlet sel -T -t -m 'rss/channel/item' -v 'concat(enclosure/@url, "→", title)' -n - | sort | while read episode
  url="$( echo ${episode} | awk -F '→' '{print $1}' )"
  ext="$( basename "${url}" )"
  title="$( echo ${episode} | awk -F '→' '{print $2}' | sed -e 's/[^A-Za-z0-9]/_/g' )"
  wget "${url}" -O "${download_dir}/${title}.${ext}"
