CLI Magic: Bring in podcasts with BashPodder
Podcatchers, the programs that download and aggregate your favorite podcasts, are popular on all platforms. Many are available for Linux, including iPodder and Podget. But the truth is that you don't need all that fancy stuff to harvest podcasts with Linux. BashPodder is a quick CLI-based GPLed podcatching client. It's one of the oldest ones out there, and may still be the best. It's hands-on, no-frills -- and a perfect example of how a few command-line statements can work together to do a powerful job.
Written by Linc Fessenden of The Linux Link Tech Show podcast, BashPodder parses the URLs of any podcast feeds you give it and saves the podcast files to dated directories. Because of its simplicity, it works on every Linux distribution, and it's cross-platform, too -- Fessenden reports that users have gotten it to work on AIX, BSD, Mac OS X, and Solaris, among others.
You might say, "Well, I'm pretty sure I can do that with wget" -- and you're right. That's what BashPodder uses behind the scenes. It's actually a very simple program itself -- strip away the few dozen comment lines and you have just 20 lines of Bash code, with wget smack in the center. An experienced shell programmer could write and debug an equivalent in an afternoon.
But there's no need to, now that Fessenden's already done the work. And you can use it to do some pretty useful stuff.
