[OT] Handy functions for ripping movies

[Ron Johnson <ron.l.johnson@cox.net>]

Hi,

While ripping a bunch of (legal!) DVDs, I came up with these bash 
functions to make the task simpler.  Hope you find it useful someday.

You'll, of course, have to modify the DEST & TARGET values to suit 
your own organizational theories.  For me, movies and tv shows go in 
separate directories

$ get_movie Jungle_Book_\(1942\)

$ get_movie Love_Crazy

$ get_video tv/z__movies 1 Halloweentown

$ get_video movies 1 Captain_Kidd

$ get_video movies 2 King_Solomon\'s_Mines

$ pwd
/data/big/video

$ dir
total 233272
drwxr-xr-x  6 me   people      4096 2009-01-25 00:25 ./
drwxr-xr-x  8 root people      4096 2009-01-23 09:39 ../
drwxr-xr-x  8 me   people      4096 2008-08-03 15:46 anime/
drwxr-xr-x 12 me   people     12288 2009-01-25 00:31 movies/
drwxr-xr-x 10 me   people      4096 2009-01-24 16:06 shorts/
drwxr-xr-x 45 me   people      4096 2009-01-25 00:30 tv/
