flvdown.sh for downloading flv video from YouTube.     在网上看到可以通过 www.youtube.com/get_video.php 下载 youtube 的 flv 动画, 于是尝试写了个脚本实现: #!/bin/bash # # @Function: # download flv from www.youtube.com # # @HOW-TO: # E.G. # flvdown.sh http://www.youtube.com/watch?v=1eOu-jVuuxo # # @Author: # HenryFour # @Date: # 2008-01-08 # how_to() { echo "Usage:" echo " flvdown.sh youtube_video" echo "E.G. flvdown.sh http://www.youtube.com/watch?v=1eOu-jVuuxo" echo "" } downflv_exit() { EXIT_CODE=$1 tmp_file_name=$2 if [ -f "$tmp_file_name" ]; then rm -f "$tmp_file_name" fi exit $EXIT_CODE } WGET="/usr/bin/wget -c " downflv_main() { flvaddr=$1 #check whether it is youtube web address if !(echo $flvaddr | /bin/egrep -q 'www[1-7]?.youtube.com/watch"?v='); then echo "addr invalid: flvdown.sh can just download youtube vidow." exit 1 fi #get the video page down webfilename="${flvaddr#*watch?v=}.$(/bin/date '+%F-%s').tube4" if ! $WGET -O "$webfilename" "$flvaddr"; then echo "Failed to download page: $flvaddr" downflv_exit 1 "$webfilename" fi #get video info from the webfile video_title=$(/bin/grep '<title>.*</title>' "$webfilename" | sed 's/^"s*<title>"s*"([^"s]"+.*[^"s]"+")"s*<"/title>"s*$/"1/') video_id=$(/bin/grep 'fullscreen' "$webfilename" | sed 's/.*fullscreen?video_id="(.*");$/"1/') video_id=${video_id%"'} video_file_name="$video_title".flv if [ -f "video_file_name" ]; then video_file_name="$video_title"-$(/bin/date '+%F-%s').flv fi video_down_addr="http://www.youtube.com/get_video.php?video_id=$video_id" #download flv video if ! $WGET -O "$video_file_name" "$video_down_addr"; then echo 'Failed to download flv video' downflv_exit 1 "$webfilename" fi echo "download flv vedio: $video_file_name" downflv_exit 0 "$webfilename" } if [ $# -ne 1 ]; then how_to exit 1 else downflv_main $1 fi

當我看到這個Shell Script的時候，我在想 YouTube 的下載方式又多了一種
而寫這一個 Shell Script 的作者對 Script 及 YouTube 也很熟悉

我看了他的 Shell Script 原碼後，是利用 Linux 的 wget 下載 YouTube 的影片

其原始 Shell Script  碼如下：

#!/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"
