当我看到这个Shell Script的时候，简直佩服作者的Shell Scripting功夫
放在这里给有需要的人
用法：将下面的代码复制然后储存为youtube.sh
CODE:[Copy to clipboard]#!/bin/sh
# $Id: youtube.sh 496 2006-06-05 23:37:35Z berto $
if [ "$#" != "1" ]; then
echo "YouTube Video Downloader"
echo "Written by Alberto Garcia <agarcia-at-igalia-com>"
echo "Homepage:
http://people.igalia.com/berto/"
echo
echo "Usage:"
echo " youtube.sh
http://www.youtube.com/watch?v=<video_ID>"
echo " or"
echo " youtube.sh <video_ID>"
echo
exit 64
fi
VID=$(echo "$1"|sed "s/.*v=\([^&]*\).*/\1/")
URL1="
http://www.youtube.com/watch?v=$VID"
echo -n "Getting $URL1 ..."
PARAM="$(wget -q -O - "$URL1"|grep watch_fullscreen|cut -d '&' -f 3)"
echo " done."
URL2="
http://www.youtube.com/get_video?video_id=$VID&$PARAM"
echo -n "Getting $URL2 ..."
URL3="$(wget -S "$URL2" 2>&1|sed -n /Location:/s/.*http:/http:/p)"
echo " done."
echo "Video address is $URL3"
exec wget -O "$VID.flv" "$URL3"
我在下面加了两行，使它下载后自动把flv转成mpg：
CODE:[Copy to clipboard]exec ffmpeg -i "$VID.flv" -ab 56 -ar 22050 -b 500 -s 320x240 "$VID.mpg"
exec rm "$VID.flv"
