First install this:

sudo apt-get install imagemagick mplayer gtk-recordmydesktop

those are the required stuff, ImageMagick, MPlayer and Desktop Recorder. Then use Desktop Recorder to capture a portion of the screen/application to use as the screencast. After the Desktop Recorder has saved the recording into an OGV video, MPlayer will be used to capture JPEG screenshots, saving them into the 'output' directory.

On a terminal:

rankun203

#统计文件数目
ls -l |grep "^-" | wc -l
#批量改名
for files in `ls *`
do
  mv $files `echo "xxx_$i.jpg"`
  let "i++"
done

/**
 * 根据文件名生成文件的 key
 * @param fileName
 * @returns {string}
 */
function genFileKey(fileName) {
  var fileKey = '';

  // 将文件名中的有效字符提取出来作为文件 key
  var realFileName = fileName.match(/[\w|\.]/g).join('');
