I am a linux advocate, I also believe in freedom in all it’s aspects. Call me old fashion but I still believe “small code” and minimal resources is the way to go. That’s why most of the apps I run have a CLI.
Here are some of my favorite CLI apps.

Pandora – Command Line Alternative

@ https://github.com/PromyLOPh/pianobar

If you’re a command line geek and/or want to keep the strain on your system as low as possible, then Pianobar is an awesome alternative. There are packages available for a number of different distros. The program itself is simple: Open a  terminal, log in to your account, and select the station you want to listen to. You can even ban a song, create a new station, view song history, and everything else you can do in Pandora right from the Terminal. Also there’s no annoying commercial every 3 songs.

cvlc: Console VLC Player

Use ‘cvlc’ to use vlc without interface. This is useful for command line playing or ripping using shell scripts. This will save lots of time.

cvlc '/path/to/my.mp3'

TTYtter for Perl

@ http://www.floodgap.com/software/ttytter/

Noooo, not another Twitter client! Yes, another Twitter client. The difference here is that you’re dealing with a multi-functional, fully 100% text, Perl command line client.

% ./ttytter
trying to find cURL ... /usr/bin/curl
-- no version check performed (use -vcheck to check on startup)
(checking credentials) test-login SUCCEEDED!
-- processing credentials: logged in as screwtape
-- checking for most recent direct messages:
[DM da0][cbqueue/Fri Sep 28 02:01:33 +0000 2007] test test
[DM da1][ttytter/Fri Sep 28 03:01:51 +0000 2007] don't forget to update the website
-- notification: API rate limit is currently 350 req/hr
-- no version check performed (use -vcheck to check on startup)
-- you are logged in as screwtape

You use the -status=... option to post a single tweet, which is more efficient (and can be made bulletproof using the -hold option):

% ./ttytter -status="Writing a letter to my nephew."

There are tons of alternative apps for the CLI
