前天和同學們在咖啡館喝咖啡聊是非，討論到家中弟妹都資源共享，但是某些隱私性的資料該怎麼處理呢？
在唸中X大學碩士班的天才同學"小仁"，推了推他的千度眼鏡很老沉的說 "A片就A片，假什麼？"
大家都不爽他的傲慢態度，便問"要不你怎麼不被發現電腦裡的A片？"
只見他拿出他半年前買的NB(筆記型電腦)，開起電源，點取他的D 槽，裡面是論文報告夾、MUSIC夾、LETTER夾、DATA夾、哩哩扣扣一大堆資料夾。
靠！偽裝這招也太遜了吧？小仁一臉不屑的說"我有需要那種偽裝的地步嗎？"
看著他點了滑鼠兩下"趴"一聲：
一本道之XXXX、無碼之草X牛奶等，一大推A片檔名歷歷在目。
回頭再看他的資料夾，小仁放Ａ片的資料夾名稱是取啥？

“搖桿驅動程式”
當場把香草拿鐵噴到他的 14.1 吋螢幕上……。
後續-----
「搖桿驅動程式」再點進去還有兩個資料夾~~
一個叫「騎兵」~
一個叫「步兵」~
啥意思??
騎兵 = 有馬(碼)
步兵 = 無馬(碼)
/dev/fb* (e.g. /dev/fb0). It behaves much like other memory devices in linux, in that you can also read and write it with normal tools. For example copying the framebuffer to a file (effectively making a raw screenshot) can be done with:
cat /dev/fb0 > somefile
