ubuntu下抓flash缓存

今天在chrome上看了个ＭＶ，想把它保存到手机上，但却找不到缓存目录。一阵百度google后，找到了神一样的解决方法，深感linux的强大。。

解决方法来自：Ask Ubuntu

可以写个脚本：

#!/bin/bashpidNum=$(ps ax | grep flash | grep chromium | grep -v "grep" | sed -e 's/^ *//g' -e 's/ *$//g' | tr -s " " | cut -d " " -f 1)procNum=$(ls -l /proc/${pidNum}/fd | grep Flash | tr -s " " | cut -d " " -f 9)filename=$1if [[ "$filename" == "" ]]; then    filename=$procNumfiecho "Copying /proc/${pidNum}/fd/${procNum} to '${filename}.flv'"cp /proc/${pidNum}/fd/${procNum} "${filename}.flv"ls -lah "${filename}.flv"

或者来个简单易懂的：

I made a little research and now I can come with the answer that is not so simple as it seems at first sight.

I searched a lot on Google, and almost everything is pointing to the ~/.cache/chromium/Default folder. It’s the folder where you should find google chrome’s cache files. But there are no big flash video files (like YouTube has), just small ones.

In the end, to answer the question, I came to these conclusions:

• First, you have to open an YouTube video and let it stream from internet.
• In a Terminal (Ctrl+Alt+T), you should get PID of Chromium that use Flash Player plugin. You can use various commands, but ps will do just fine: ps ax | grep flash.

• Once you have this PID you can find out the name of video file that just was streamed on Youtube:ls -l /proc/[*PID*]/fd | grep Flash. You will see as result something like this:

  lrwx------ 1 [*user*] [*user*] 64 mai 2 09:48 [*video file name - is a number*] -> /tmp/FlashXX4PeKRY (deleted)`

  And here is the answer of the question: the last video file streamed on YouTube and cached on the system is:

  /proc/[*PID*]/fd/[*video file name - is a number*]

• Now, if you want, you should copy them anywhere on the system:

  cp /proc/[*PID*]/fd/[*video file name - is a number*] ~/Videos/[*new video file name*].flv

  And now you have the last video watched on Youtube in your personal Videos collection.

另外，mac下chrome缓存目录为/Users/账户名/Library/Caches/Google/Chrome/Default/Cache。
